WELCOME TO PATAGONIA.
WELCOME TO GLACIER TO GLACIER 2025!
Dear #Ratracer,
​
Patagonia Glacier to Glacier is an extraordinary journey from the Laguna Torre Glacier in the north to the world famous Perito Moreno Glacier in the south. With a constant back drop of jagged mountain peaks and never-ending epic views every day in isolation is amazing but stitched together as they are on our route, this is one trip that you will never forget. This document is designed to give you all the information you need and hopefully answer any questions you may have.
​
Believe me when I say the Rat Race event team are just as excited as you are to be getting on a plane in a few months time and bask in the glory that is Patagonia once again.
​
For now, take the weight off, grab a cuppa (or something stronger!) and read on. Welcome to the adventure and see you all this November!
​
Rob Atkin
Event Director, Rat Race Glacier to Glacier​

Accommodation: Hostel Pioneros del Valle
​
DAY FOUR / MORE AMAZING TRAILS
24th November 2025
We hit the local trails again and make our way to the Laguna Torre glacier, a spur of the mighty Viedma Glacier.

Ascent: 750m (2460 ft)
Video: HERE
Meals: Breakfast and dinner provided. Some basic on-course snack provision will be supplied also via our pit stops. You should plan to be largely self-contained and take some snacks and fluids that work for you whilst on the foot stages also.
Accommodation: Hostel Pioneros del Valle
​
DAY FIVE / ONTO THE BIKES!
25th November 2025
​​
Leaving El Chalten, the route goes west to east, on a desolate tarmac road, before swinging south onto Ruta 40, Patagonia’s legendary arterial road. This is fast cycling, if the wind is behind you! It’s also great fun and you’ll have the chance to pit your strength against the unpredictable Patagonian winds. There is also very little traffic and only 1 junction! Our destination is the legendary Parador La Leona, a riverside saloon made famous as a hide-out of Butch Cassidy and the Sundance Kid. We camp here in tents that we provide. You provide a sleeping mat and sleeping bag. The site has basic showers.
​
Discipline: Bike
Distance: 110km (68 miles)
Ascent: 240m (787 ft)
Day 3: HERE
Meals: Breakfast and dinner provided. We will operate mobile pit stops on the bike leg, with plenty of snacks and drinks available. Look out for our local Empanadas!
Accommodation: Camping at La Leona
DAY SIX / INTO THE WATER
26th November 2025
​
Today’s journey is split into 2 sections, kayaking and cycling. To manage kayaking safely and maintain staff/ participant ratios, we split into 2 groups. You will either kayak first and then cycle, or vice versa. The journey here is kept complete, so you will either kayak from A to B and then Cycle from B to C, or you will cycle from A to B and kayak from B to C. No section of the journey is missed. You get the picture! Both paddling sections are similar in tempo, water volume and view. Using our tandem sea kayaks, 2 of you will paddle together which makes for a social and speedy journey.
NOTE: Patagonia is of course famed for its winds and whilst the kayaking will proceed in many conditions, high-speed headwinds may force us to change the plan, as progressing down the river in high winds is pretty hard work. Please understand that if we do change the plan on kayak day, we are doing so with your safety and enjoyment in mind.
Discipline: Kayak / Bike
Distance: Kayak 35km (22 miles) / Bike 40km (25 miles)
Ascent: 310m (1017 ft)
Video: HERE
​
Tonight is a wild camp, so it’s a wash in the river if you’re brave enough to take on the chill!
​
Meals: Breakfast and dinner provided – we will eat tonight around the campfire and likely will enjoy a traditional home-cooked Argentinian stew (veggie and vegan option available of course). You will largely be self-contained in the boats but we will operate a shore-based ‘pit-stop’ on the kayak leg, with plenty of snacks and drinks available for you to enjoy when you come ashore.
Accommodation: Wild Camping on the riverside.
​
DAY SEVEN / BACK ON THE BIKES
27th November 2025
​
Back on the bikes we head back to civilisation and pass through El Calafate before swinging uphill and out of town. Gravel roads lead us to the the stunning location of Estancia Mitre, set tantalisingly close to but still out of sight of the mighty Perito Moreno glacier.​
​
Discipline: Bike
Distance: 97km (60 miles)
Ascent: 620m (2034ft)
Video: HERE
Meals: Breakfast and dinner provided. We will operate mobile ‘pit- stops’ on the bike leg, with plenty of snacks and drinks available.
Accommodation: Rustic dorm-style beds and some camping at Estancia Mitre
​
​DAY EIGHT / TO THE GLACIER!
28th November 2025
​
Our final day sees us enjoy a unique cycling experience, 39km of closed roads through the Parque Nacional los Glaciares to reach journey’s end at the mighty Perito Moreno Glacier. It’s medals and high fives all round with this stunning backdrop for photos. The local guides will share their knowledge as we get up close and personal with this beast of nature. Together we will travers the walkway that gets us even closer to the glacier face. This really is a fitting end to a quite unbelievable adventure. After some high fives and perhaps a celebratory beer or two, it’s then back off to El Calafate for our final night together. Enjoy a slap-up celebration dinner, plenty of Malbec and a cosy night in a great local hotel.​
​
Discipline: Bike
Distance: 39km (24miles)
Ascent: 420m (1378ft)
Meals: Breakfast, packed lunch, celebration snacks at the finish line and a celebration dinner provided, plus a celebration drink on us.
Accommodation: Hotel Konke, El Calafate​
​
​DAY NINE / JOURNEYS END!
29th November 2025
​
After our final breakfast together, it’s time to head to the airport at El Calafate for return onwards travel.
We will offer one communal transfer in the morning and will advise on the transfer time once we have collated all departing flight info via the forms you will submit to us. (See more in this document about the forms we ask you to fill in). If you are hanging around in Patagonia or if you have later flights, you are welcome to make your own transfer arrangements with the hotel, or locally.
​​​
DAY-TO-DAY: WHAT TO EXPECT
STYLE OF TRAVEL
With 3 different disciplines, how we support each day varies according to what we’re doing.
The 2 run/trek days are mostly self sufficient due to being inaccessible by vehicle. We have medical and support staff on the trails and provide small pit stop support but it’s not a full on service as we have to carry everything in. You should expect and plan to carry 2+ Litres of water on each of these days.
The cycling days have full support. Lead and sweep vehicles plus 2 or 3 pit stops depending on distance. Each pit stop will have water and snacks, with something more substantial at the designated lunch stop.
The kayak stage will have a midway rest stop for you to stretch your legs and grab a snack and a drink that you’ve taken with you.
You go at your own pace each day, be with others, be on your own, you choose. We will not stop you unless you look unlikely to finish in daylight. This means there aren’t formal cut offs. However, if it is likely that you’re going to run out of daylight before finishing the stage, we will work with you to ensure to complete as much as you can and stay safe.
​ACCOMODATION
Accommodation throughout the trip varies from a hotels to a wild camp. Here is an overview of what to expect.
Nights 1,2,3,4 – Hotel Pieoneros, El Chalten – double/triple/quad rooms in the heart of this small town, gives us the perfect base to establish the event. Its 4 nights here.
Night 5 - Parador La Leone is a classic roadside restaurant. We camp in the trees behind the parador. We provide and put up the tents, you just need to bring a roll mat and sleeping bag. There are some basic showers.
Night 6 – A true adventure camp on the edge of the river. There is a long drop toilet and a great view! Same tents and set up as the night before. We’ll enjoy some open fire cooking and hopefully an amazing sunset.
Night 7 – Estancia Mitre is the prettiest location of the week and a real treat to stay on a working farm. The sunsets are amazing. Beds are spread across different buildings and some people will need to camp again but the location, food and wine make this an unforgettable evening.
Night 8 – Hotel Konke, El Calafate – Back to civilisation and a central hotel in town to allow us to enjoy all that El Calafate has to offer.
FOOD & BEVERAGE
All meals will be provided whilst you are on our itinerary. Typically, this means breakfast, lunch (at pitstops) and dinner. There will sometimes be a pay bar and from time to time, some beers and other beverages will come your way from us, too!
Pit stops are different on trek days and riding days.
You need to be self sufficient on the trekking days due to the lack of vehicle access to the trails meaning we can’t deliver a regular pit stop. There will be a sandwich station in the morning so you can prepare your own lunch and take snacks for the day. We carry in water for top ups and some snacks but need to share the load with everyone being self sufficient.
Cycling days have regular pit stops with 1 being dedicated a lunch stop with more substantial items. Expect water, fruit, sweet and salty snacks. Plus the odd Empanada!
You should look to augment these Pit Stops with your own snack supplies and you should very definitely provide your own hydration, electrolyte and sports nutrition supplies. This will be important throughout your adventure. At the end of the trip, we will provide dinner and some celebration drinks.
​
ALCOHOLIC DRINKS & EXTRAS ​
Where we provide meals as part of the general event service, we will not include alcoholic or soft drinks as standard and these must be provided by yourselves. See more on local payments, below.
​
At some of the accommodation, there is a pay-bar where you can buy drinks and small snacks.
We will provide you with some beers at certain locations, to celebrate a job well-done. That is a Rat Race tradition! These will be at the discretion of the organisers, however, in general, you should expect to pay for alcoholic and soft drinks.
​
ABLUTIONS & HYGIENE
There is a mixture of accommodation within the itinerary. It is therefore not guaranteed each evening will have a shower facility. e.g. camping nights. Therefore, you should keep to a high level of personal hygiene by using wet wipes, washing with minimal water and always keeping hands clean. Check wounds, rashes, and blisters regularly for infection. 
Pit stops will not contain toilets, so if you need to go out on the course, be prepared.
​
The firm advice is always to ensure you are ‘self-contained’ with toilet roll and with anti-bacterial handwash gel for the trail. 
THE ROUTE
The route we have plotted takes you on an extraordinary adventure, revelling in some of the most famous sights of the area – at the same time as taking you off the beaten track to experience the very essence of this wild and alluring slice of paradise!
​
TRAINING & PREPARATION
A multi day, multi-sport journey demands an all round level of fitness and strength. If you maintain a regular schedule of aerobic and strength activity you be fine for this event. To give you a guide as to the level of training required see our multi sport training plan HERE
​
ROUTEFINDING & GPS
The manner in which you will make your way through the course is to follow a GPS device. We recommend you bring your own GPS device that you are familiar with and have practiced using prior to the event. If you DO NOT have your own device/s, we do have some options – and we would ask that you read this section in detail so you understand what we are advising/ recommending and what we have available to assist you, if you so wish.
If you would like to rent any of our available devices, you must let us know in the pre event admin form.
We will also provide all participants with a GPS tracker, which is a separate device and is covered in the relevant section below.
You will also be required to have your own phone, with battery pack back-up for charging in the field.
There are therefore multiple devices under consideration here.
-
Navigation/GPS devices
-
Tracker
-
Phone
​
Let's start with GPS devices.
​
1) BIKE DEVICE
-
If you have your own bike-mounted device (like a Garmin Edge, for example) and are comfortable with its operation, this is the preferred choice whether you have rented a bike from us or not. We will provide GPX files much nearer the time for you to upload to your own devices.
​
-
A mobile phone with a power pack, plus a bike mount is a perfectly reasonable and indeed very user-friendly solution here too, provided that you can ensure the combination is waterproofed. This was popular with riders in 2024 and it allows you to use your own technology, with which you are already familiar. You also do not have to invest in any expensive tech devices. You may need to purchase a handlebar mount for your phone, but this is easy to source and inexpensive (and handy for day-to-day use at home, too!)
​
-
For participants who do not have their own bike-mounted device and/ or do not feel comfortable using their own phone, we will be able to rent you a handlebar-mounted Garmin Edge bike navigation device. You will tell us whether or not you need one of these in the admin form, linked below. This device attaches to your handlebars and you follow it like a satnav device. It does not have a basemap and you follow a line on the device. These are £35 to rent.
It should be noted, that the bike ‘nav’ is very simple. On the first bike day, there is literally 1 junction. On a later day, there is a section where you ride through El Calafate town but this is as difficult as it gets. It is very intuitive. So back to the advice above, if you have a decent phone and can mount it to your handlebars and waterproof it, this is a very good solution.
​
2) RUN/TREK DEVICE
-
For the foot section, if you have one, your own GPS watch is the go-to advised piece of kit to use and we will again provide GPX files to use on your own device.
-
For those who do not have a GPS-enabled watch, you can hire a GPS watch (Coros Apex Premium) from us.
-
These devices will have the route uploaded onto them and have extremely good battery life. These can be chosen to be rented via the admin firm linked below. Coros watch hire is £50.
-
For those using our rental equipment, we will provide guidance in the use of these devices upon arrival to El Chalten for Registration.
-
The webinar will also be a great opportunity to learn more about the navigational devices recommended for use in the event.
​
3) TRACKER
Separate from the devices above, we will issue everyone with a tracker, which both provides a tracking function for us to keep take tabs on where you while out on the course; and for your supporters to track your progress.
​​
(Please note that this is a separate device from the GPS navigational devices – it is very light and small and will likely attach to the outside of your bag with tape, or stuff into a pocket. More is explained on tracking in the section below).
​
4) PHONE
It is also mandatory to be carrying a phone at all times on the trip, with the ability to charge it via portable battery pack. This device can absolutely be your primary nav device on the bike stage, mounted to your bike and waterproofed accordingly. You may also use it as a back-up on the trek stage.​
​
We will ask in all cases that you will upload the route files to your phone, to use as a handy back-up. For both the bike and trek routes, a phone with the route showing on an App is a very good choice, provided it is waterproofed from the elements.
​​
If you are keen to practise using your phone to navigate, download a suitable App such as Garmin Explore or Garmin Connect (there are loads of great Apps but we use these a lot) and practise uploading GPX files to the phone and following them in the App. It really is easy once you know how to get the files into the App on the phone. If you want assistance, please email events@ratrace.com and we will be happy to talk through any of the tech side of things for those who are not comfortable with it.
​​
WAYMARKING
We will NOT waymark any of the route.
​
ON THE WATER...
Keep the kayak pointing downstream! You do not need to navigate on the river and you will be in a group with our water safety team at all times. However if you wish to track your progress down the river, a GPS watch is the recommended piece of equipment to do that with.
​
In general, as you can see, this event is operated with GPS as the main method of route guidance. If you do choose to use your own devices (recommended), it is important that you are well versed in the usage of your own devices and that you are confident in their battery life and reliability.
​
ROUTE GPX FILES
We will also make available route GPX files for you to upload onto your own devices as you see fit. These files will be provided much closer to the commencement of the event, once we are satisfied, we have the definitive version to share. Experience has shown that we will never share the file until it is the final, final, final version. Or else we end up with version control issues that are hard to resolve. We do not anticipate major route changes from the route published, but never say never.  These files will be issued at the 1-week out email phase. ​
COURSE CUT OFFS & WITHDRAWALS
This event is not about cut-offs. But, having a ‘cut-off’ and a ‘sweeping’ structure is an important part of our Event Management Plan and Risk Assessment processes. Cut off times are independent of any other factors that occur earlier in the course such as start time, injury, going the wrong way, time taken at Pit Stops, head winds; and whether it is your fault or not. We understand that missing cut offs can be tough to take but please remember this is not the crew member’s fault that breaks the news to you, should it happen to you. Please also remember that if this does happen to you, the Event team’s decision is final.
​
If you are cut off, there will be no option to re-start from where you were cut off the next day. (The event only ever moves forwards). You may however re-start the next day from the official re-start location; subject to the discretion of the event team.
​
There are a number of reasons why you may be cut-off or withdrawn from the event. These could be medical, pace, kit, personal or other factors.
​
It is OK to retire and to be taken forward to the overnight accommodation. We’d rather you re-started the next day vs suffer meaninglessly and spoil it for yourself. We call this being ‘boosted.’ As far as the time available goes to avoid a cut-off, there is no ‘set’ cut off time each day. (i.e. Time limit or published time). Instead, we require all participants to be at the finish location before nightfall. If this is looking unlikely you will be ‘swept’ forward. That is the cut-off. Above all else, please remember, this event is not about cut-offs. It is about getting the most out of this magical environment. We will not cut you off and sweep you forward unless we really have to. And if we do, it is for your own safety.
​
‘BEDDING DOWN INTO THE COURSE’
It is probable that when you set off on the adventure on day 1, the first hours of the first day may be a bit hit n’ miss. Pace, temperature regulation, kit selection, footwear etc. All to be expected. Embrace that ‘bedding down into it’ phase and listen to your body and to your kit. Expect some unexpected phenomena (not UFOs, just unusual kit or equipment issues that you may not have quite been expecting). Use this time to just get used to the environment, the gear and the temperature. Go with it and relax. By Pit Stop 1 or 2, you’ll have worked out enough to be comfortable…
COURSE CHANGES
The nature of an adventure is that sometimes, the certain becomes uncertain! That is all part of the adventure. Whilst we will always strive to pull off ‘Plan A,’ it may well be that for any one of a number of reasons, we cannot do so and we need to wheel out Plan B, C or D. We do line up contingencies for many eventualities of course. But it is worth knowing that the course may change if we deem it prudent for your safety or for other operational or weather-based reasons and we must always reserve the right to do so. Ultimately our skill and judgement in organising such events is part of why you are entering, so we must be able to exercise this on your behalf where we deem it necessary. If we do have to make a route change, we will strive to inform you in good time (if that is possible). Usually, these unforeseen changes simply add to the flavour of proceedings and provide for a good story to tell at day’s end!
​​​
MANDATORY KIT
Some of the kit listed is to help you have a safe experience and have the best chance of finishing. Some of this kit is to ensure that if you are unable to continue without our assistance then we can be confident of you having the level of equipment required to keep you as comfortable as possible whilst you wait for that assistance. Some of it is simply to keep you from perishing. It is a serious list and we know everyone knows this, but we ask that you please do work with us on this. Please do not skimp on kit.
​
​
​
​
​​
EL CHALTEN KIT CHECK
During Registration at El Chalten, we will be conducting a kit check as part of the Reg process.
As a minimum, we will be checking:
-
​​Sleeping bag
-
Roll mat
-
Windproof and/or waterproof upper body AND leg cover
-
A wicking tee/base layer/long sleeved wicking layer
-
Mid-layer (e.g. microfleece)
-
Bivvy bag
-
Personal first aid and footcare kit containing all mandatory items
-
Running pack and hydration system
-
If bringing your own bike, we will need to see your tool kit, spare parts and puncture repair kit (see cycling kit list for full list)
-
Bike helmet
-
Navigation device (if you have chosen to hired one from us, this will be issued at registration - you can read more on the navigational device requirements and hire option in the Route section HERE)
You may be asked to show any other items from the mandatory kit list. Clearly at this point, the die is somewhat cast in respect of where we are geographically and the ability to ‘fill in any gaps’ is therefore heavily reduced; however we will look to assist where we can, in the event of major kit catastrophe. If you do not have the appropriate kit with you when you register in El Chalten, you may not be allowed to participate. We have devised the mandatory kit list for your protection and safety, and we will not be able to make any exceptions on required items. If you have any kit questions, you can bring them to the webinar or contact us via events@ratrace.com and we will be more than happy to help!​

WHAT’S THE WEATHER LIKE?
This is the ‘hottest’ time of year in Patagonia (it is the height of the austral summer) but it never gets ‘hot, hot.’ Highs of 15 – 22 C are the norm but it can be much cooler, especially in the mountains. What is also inevitable at this time of year are the notoriously strong Patagonian winds. Whilst it is arguably a bit more sheltered in amongst the mountains, the bike stages on the Steppe are very exposed and it can be windy on the river, too. Which means it could be dusty, windy, rainy, cloudy, sunny. Basically it’s a bit like Scotland. On steroids. Changeable is the word and you should study this kit list carefully. It has been prepared with this destination and with this event specifically in mind.
​
SUN PROTECTION
Whilst the heat of the day will not be fierce, a wide-brimmed sunhat, sun-cream and lightweight and breathable fabrics (ideally with SPF protection) should be packed. As should sunglasses with at least Cat 3 protection. You will be outside for a good long time after all.
​
WET WEATHER GEAR
The chances of rain are high and you should definitely invest in decent waterproof garments. Items specific to running and cycling disciplines are a bit of a luxury but will provide more comfort. These garments are also windproof which will provide a lot of warmth every day too. Taped-seams on waterproof garments are essential. This provides you with absolute waterproofing, vs garments without taped seams will will eventually leak.
​
BIKE KIT
If you are bringing your own bike:
As well as supplying your own bike, please bring everything you would need to support yourself on that bike – pedals, footwear, tools, pump, puncture repair gear, helmet and bike clothing for dry AND wet weather conditions.
​
Spare Parts – I’m sure you’re all aware of the difficulties in the bike supply chain after the Covid period. This has affected parts as well as availability of new bikes. If you are bringing your own bike, for your own bike you should try and bring with you the following items: Rear Mech Hanger, spokes, chain, brake pads, a selection of nuts and bolts relevant to your bike, plus 1 of each cable type that your bike uses. With the assistance of our mechanic these should cover most issues and keep you rolling. Please bring it all in a bike box or bag (a bike box is preferable to a bag as they just do not damage as easily in transit – planes, vans, etc).
If you are renting a bike from us:
We will be providing you with a Marin Gestalt Gravel Bike with a frame commensurate with the size you have indicated to us. These are robust mid-range gravel bikes: Great brand, Shimano components, brake-mounted gear shifters. You can check them out HERE.
You will need to bring all clothing that would need to support yourself on that bike – do bring your own pedals if you wish, although of course we will provide pedals (flats) as standard. Bring also footwear, a helmet (see below) and bike clothing for dry AND wet weather conditions.
EVENT REGISTRATION PACK
In El Chalten, there will be one event pack issued per person. Your Adventure Pack will contain:
​
Bib Number
You should try and wear this on the outside of all clothing so that it is always visible. A good place to wear it is on the back of your event pack, if you are carrying one.
​
Numbered Bag Tags
For your overnight and race bag. These must be attached to your bag before handing them over to our crew to transport each day.
​
Event T-shirt & Rat Rag
If you do not select your t-shirt size in advance, you will automatically be allocated a Large.
​
Tracking Device
We will issue the tracking device and demonstrate its use.​
​
HELMETS FOR RENTALS
For those renting a bike with us, a helmet is not provided. You MUST bring your own helmet. If you don’t have a helmet you will not be allowed to ride.
SPARES, TOOLS AND SUPPORT FOR RENTALS
We will provide a small tool kit for use with your bike. We have a local bike mechanic with us on the event and they will be able to assist you with both set-up and ongoing maintenance of your bike whilst on the event. If you do have a multi-tool and a handheld pump in your gear at home, we would always encourage you to bring these so you are self-contained with some tools and equipment that you are familiar with.
TUBE BAGS, SADDLE BAGS ETC
If you wish to accessorize your bike with such items, do please bring these with you. We do not provide any bike-attachable bags as standard.
CAMPLIFE
For our accommodation, we will use a hostel in El Chalten, a lovely hotel in Calafate and a rustic Estancia on the penultimate night. The other 2 nights are under canvas in our tented camps. We will provide the tents. You will need a sleeping bag and a roll mat or similar. Also remember, these are still nights under canvas, so if there are creature comforts that you wish to bring to augment your comfort levels, please do so. We would also advise bringing a towel just so you are self-contained on that, plus a power bank for electrical items and phone; and toiletries. A pair of sandals or flip flops are also pretty invaluable for camp and for kicking back in the evenings, just to air those tired feet. These items are reflected below as recommended items.
​
NUTRITION
We do insist that you have some buffered electrolyte tablets (like Salt Sticks) and other electrolyte replacement items with you – these are invaluable to re-instating equilibrium when you are exerting yourself. Experience shows that good electrolyte management can make or break these types of endurance activities. Whilst it is not massively hot, you will be getting moisture beaten out of you by the wind. Some dissolving electrolyte tablets for adding to your water; and the carrying of other sports nutrition supplies is recommended just to have in your grab bags. This allows you to be self-sufficient with items that work for you, at all times. We will have food and drinks at the pit stops, but we always ask that you provide your own sports nutrition as it’s a personal thing and it is by far the best approach to be self-contained and fully comfortable in such matters.
​
Q&A WEBINAR
The Q&A Webinar on Monday 6th October at 1800 UK Time is a great opportunity to ask any kit related questions and ensure you are fully prepared for the adventure ahead.
​
TRACKING DEVICE
During Registration in El Chalten you will be issued with your tracker. It will be in a waterproof dry bag. It is your responsibility to look after the device until you return it to us at the finish line in exchange for your medal. This device not only allows those at home to follow you on the route, it acts as a tracker for us too, meaning we can see where you are throughout the event.
​
​Tracking will go live on the first morning of the event. The link will be available via Open Tracking here: https://results.opentracking.co.uk/ and will also be shared in the event Whatsapp group closer to the time.
​
The trackers rely on GSM signal to report, (which is generally patchy particularly on day 1 & 2 so there will frequently be a delay on tracking).
Sometimes, our team back at base will increase or decrease the reporting frequency, so those watching at home will sometimes not see your dot moving, or see you moving very slowly. Or they may see you adrift from others in the group (for example if you have not turned the tracker on!). 
​
It is REALLY important that you ensure anyone watching at home knows this, for their own peace of mind and for our own safety systems. Experience shows that if someone watching at home does not understand this, they can sometimes unwittingly commence full rescue missions by panicking, calling in the cavalry and sparking confusion for us as organisers. As such, it really is a very important point to note.  ​
​
As with any GPS units that you use from us, you must return the tracking device at the end of the event or whenever a member of staff asks for you to do so (for example to check a setting or to charge it) and as with all electronic devices, there is a replacement cost for loss or damage. For the tracker, it is £150 so please do look after these units.   
​
VERY IMPORTANT: As we have stated, the reliability and operation of the tracking devices in this environment is likely to not be 100%, 100% of the time. As far as our safety system is concerned, we know that and we have considered that as part of our other overarching plans and risk assessment.  
​
​For those watching the tracking at home, it is important you explain that the trackers are not always going to give a fully accurate reflection of exact locations. What can happen, (if this is not communicated on the part of the participant to their supporters), is that where people see a tracker displaying erratic behaviour or not moving, this manifests in undue worry. Over a number of days, this worry can turn to panic and raising of unnecessary alarms, from the comfort of sofas in the internet-equipped watching world-at-large. We require you to ensure that, should you decide to share the tracking link, you are unequivocal in this explanation to your supporters. We cannot afford for an international incident to be commenced as someone sitting at home in front of their desktop has decided to contact the Emergency Services as they cannot see your dot moving. It really is a deadly serious point we are making here and we thank you in advance for making this clear to your supporters at home. 
BAGS AND BIKES
BAGS
There are 3 bags to be considered for this journey:
​
1.General ‘overnight’ bag (Holdall, rucksack or duffel) for spare and general kit: Please try and limit to noo more than approx 23kg pls. (This also happens to be the standard allowance on most economy airline tickets). This bag will go forward on each stage and will be available when you get to the overnight location, each night. So you will not see this bag during the day, until you arrive at those locations. We will store it for you while you are on the route. This MUST be a soft bag and not a hard suitcase.​
​
2.Daypack or running vest: This is the bag you will carry with you when you are on the run/ trek stages so you will need it on days 1 and 2. It should contain the mandatory kit, spare clothes, food and water. You can choose to also use it on the bike stages if you wish and even take it with you on the kayak stage, if you wish (although that is not required).​
3.Transition bag: This can be a small duffel, it can be your daypack itself or any other type of soft bag or dry bag. You will keep this on the vehicles during the day and it will typically be accessible at 1 designated point or Pit Stop, each day while you are on the course. Usually this at the middle (approx. lunchtime) Pit Stop. It will also be used as a ‘transition’ bag when you swap between biking and kayaking, for example. You can keep changes of clothes, dry socks, extra bike spares and tools, scooby snacks and hydration supplies in this bag.
Please note: This bag is NOT accessible on any of the trekking stages as that is very much a self-contained mountain environment. This bag will feature on the Bike and Kayak stages and will be carried in one of our vehicles. It will then be available when that vehicle reach accommodation/ camp later on in the day/ evening to replenish for the next day.
​​
BIKE RENTAL
Bike rental has now sold out.
Our bikes are Marin Gestalt Gravel bikes and were purchased brand-new in 2023. They are a very good steed for the job, given the terrain and the weather conditions you will experience.
NOTE ON RENTAL BIKES, CARE AND MAINTENANCE
Please do bear in mind, whilst these are excellent gravel bikes, it is of course not your own bike. Which means it will likely feel different. You may ride a shiny top-of-the-range speed machine at home; or perhaps it’s a Raleigh Grifter with spokey dokeys and a shopping basket on the front. Either way, the rental will feel different to your own bike. And whilst it is brand new, it may of course break down, pop a flat or have some sort of mechanical. Our event team contains a local bike mechanic and an expert UK bike mechanic flying out specially to work with you all on the event too. They will do their best to get you rolling if you have a mechanical and they will have tools and spares on board. It may be easiest at the roadside that if something cannot be fixed roadside, they may simply hand you a spare bike to continue the stage on. We will carry a minimum of 1 medium and 1 large spare for use in this instance.
Like any piece of equipment however, the better you treat it, the better it will treat you. We do ask that you are proficient in being able to change a flat at the roadside, as this will help you to get going quicker and will help our team in allocating resources while the course is live.
MEDICAL & SAFETY
MEDICAL OPERATIONS
Our team is there for you in case you have an incident with which you require assistance. The team will shadow the progress of the adventure each day in vehicles or on foot (whichever is most appropriate given the days activity) before establishing a medical clinic each afternoon/evening at our overnight accommodation. Whilst the medics are there for ‘what ifs,’ they are also a great source of preventative advice; so please do use them to ask questions and check best practice, particularly in suspected foot injury or issues such as blisters.
​
MEDICAL SCREENING
At this stage we are inviting you to have a medical screening process, which can be completed via the link HERE. Please complete this as soon as possible – and certainly please, no later than 21st September 2025. If you do have any conditions that you feel we should know about, however small you feel it may be, please do share this with our Medics. Experience has shown that early pre-screening can assist both us and you greatly in enabling the care you need pre and during the trip. If you do not share information on conditions which are likely to affect your participation or decide to share them very late in the process, we are all under pressure and we will always reserve the right to cancel your participation if we feel there is a medical issue that may affect yours, or others’ safety. So please, do share anything and everything you feel our team should know about, at the earliest opportunity.
IMPORTANT NOTE ON SUBMISSION OF DOCUMENTS AND MEDICAL INFORMATION:
​We are very fortunate to have an excellent Medical Director providing oversight, planning and screening on all of our international trips, who in turn engages seriously professional and qualified staff to join you on the trip. Rat Race also conforms and has been audited to the rigorous BS8848 standard of expedition management. This means our approach to all things safety and medical is extremely thorough and it is designed throughout with your best interest at heart.
​
Your medical screening details will be sent direct to our medical team and under medical confidentiality rules, this will only be shared with our medics and no-one else. If they decide this is info that is in the best interests of everyone for us as organisers to be privy to, they will seek and gain your consent before doing so. It is therefore important you complete the link to the medical survey only which can be found HERE. Do not send Rat Race medical information direct. If you have any queries at all on the medical side of things in relation to this event, you can email our Medical Director, Dr Patrick Musto confidentially on office@trailmed.com and he and his team will assist.
TRAVEL MEDICINE ADVICE
As well as being a practising NHS Emergency Care Doctor and Expedition Medicine Specialist, Dr Musto is also a qualified travel medicine practitioner. Please view the Travel Medicine Advice PDF HERE.
SUN & HEAT
Please carefully review our Sun & Heat Safety Guidance issued by our medical partner Trail Med.
​
EMERGENCY PROTOCOL
In the event of a true emergency or serious incident you will be notified of protocols at the pre-event briefing in El Chalten. If you are with an injured party whilst on the route, stay with the casualty and await assistance. In the event of a non-emergency incident but for which action is requested from the organisers, then you should place a call (we will give you numbers) or if no phone reception, you should send a message forward to the next Pit Stop with another participant if possible and/or await an event crew member approaching via vehicle/or on foot from behind. This might be medical, logistical or kit/ equipment breakdown as examples. We politely ask that you stop and help someone that is in difficulty – you will be the first person to find them – remember to take note of time, place (number of km, or minutes/ hours from last Pit Stop) and participant number/ name at the incident site. Remember we are all in it together and we are in effect one big team.
We will give more information on these procedures when we are all together in El Chalten. It is relevant to note that phone reception is patchy in several places and our systems do reflect this. We use satellite communication devices as part of our safety system, but no communication system is absolute in this area, so we rely on you to become part of our safety communication system where appropriate, particularly in the mountains. This will all be explained when we get together and will be very clear.
POOR WEATHER CONTINGENCY
Patagonia is known for its varied weather conditions. All four seasons can be felt in one day. Please be prepared for the multiple weather conditions and temperatures ranging from hot to cold. The terrain and altitudes along the route will also have an effect on the temperature. The event will proceed in many conditions, but if it is deemed unsafe to continue due to weather conditions or any other factors, the event will be halted at the current accommodation location. If required or possible, we will await more favourable conditions to re-commence. This may result in some stages being cut short or cancelled in their entirety in order to achieve forward progress within the time available.
​
In all cases, the decision of the Event team is final in these matters. We will monitor weather and general course conditions throughout and rest assured that any decision we do make in this regard is only ever made with the safety of event participants at its core.
​
But please do understand that the very nature of such an undertaking in such an environment requires us to plan (and deploy) contingencies and we cannot therefore guarantee that the exact itinerary as laid out on the website and in this document will be achieved. Such is the essence of adventure!
​
INSURANCE FOR YOU AND YOUR EQUIPMENT
We have asked that you have in place Travel Insurance cover and specified Evacuation cover to last for a minimum period of the event duration for the days you are with us on the published itinerary. Evacuation and medical expenses cover should total no less than $500 000. A copy of this cover/covers (if separate policies) is required to be received by us by 21st September 2025.
​
​We recommend that participants have insurance to cover damage, loss, theft, injury and non-attendance. Rat Race cannot accept any responsibility for the loss of, theft, or damage to any Participant property or the circumstances of Participant non-attendance. Within the 12-week departure window, we cannot provide any transfers and, in all cases, we cannot entertain requests for refunds. We respectfully remind all participants that unforeseen circumstances preventing attendance is what travel insurance is designed for and is the reason for this as a strong recommendation on such undertakings.  
​
Some suggested providers are as follows:  
 
For UK and Channel Island residents Rat Race’s own insurer brokers have a brand-new product: https://www.mannbroadbent.co.uk/sports-travel-insurance/. 
 
Note: This is Rat Race’s UK-based insurance broker, specialising in the leisure insurance market. This is a specialist sports travel cover product; however, Rat Race is neither an insurance broker or underwriter. We can recommend Mann Broadbent wholeheartedly as good people to deal with, but please remember that this is not a ‘Rat Race product’ and we have no say whatsoever on claims decisions made by the insurers, in the event that you raise such a claim via one of these policies.  
Other providers: 
​
Note: We have no relationship with any of these providers, but previous customers have found them reasonable to deal with regarding some of our similar Bucket List challenges.  
 
Note: For all insurance, please remember that cover is offered based on several factors, (the nature of the event disciplines being one of them), but your own insurance profile, age, health and other details form a big part of this. As such, we are always happy to provide details to insurers in support of cover requests from customers, but we cannot influence their decisions as to whether to offer cover to individuals.  
​
EVACUATION PLANNING
You have already been made aware that this is a serious undertaking in remote terrain. For the bike stage, we have vehicles in support. On the trek and on the kayak stages, there are some locations to which we can get a vehicle but in general, these are far less accessible. You need to be fully aware therefore that an evacuation from the event where vehicle access is not possible is an extremely serious undertaking. In the event that such an undertaking is deemed to be required, it may be that YOU become part of the safety system. We will reserve the right at all times to call upon members of the Event, alongside crew, to assist in any evacuation activity whatsoever required in order to remedy the situation as quickly and decisively as possible. This may involve diverting off the route, assisting with casualty-bearing and load-carrying, or other duties.
​
You should also know that the evacuation time at certain parts of the course could be considerable. It is important that we state unequivocally that we cannot remove all risk from such an undertaking nor would we state such. You are entering an area where the remoteness of the undertaking and the slowness of possible evacuation could result in Death.
​
Mitigation of such scenarios is our number one priority. Your ability to reduce the risk posed by trauma is key: Taking your time, particularly on bikes and on foot, plus steps such as descending rough ground in a carefully controlled manner are all part of this mitigation against injury. Recommended use of trekking poles for example will also help on the trekking section. You must take your time, undertake each event phase very much with a clear understanding of the environment you are in and come to the table with a team mentality on this one. That way, we will stay safe and we will mitigate and reduce the risks outlined above.
​
GENERAL SAFETY AROUND VEHICLES
This event takes place on a mix of trails, paths and roads. There are vehicles, this is not a closed road event. Vigilance must be always taken.  
LITTER
We want to show that this event has exemplary control of littering. Please help us achieve that. Pack your litter into your pack, pockets or nearby bin bag at a vehicle. No exceptions. Patagonia is a beautiful environment, and our absolute commitment is to keep it that way. 
​
MUSIC PLAYERS
While these are allowed, please control their volume according to your environment. Use your judgment at all times when listening to music or audiobooks. Please also be aware that if you cannot hear general voice levels you might miss instructions or warnings from crew, other participants or approaching vehicles. We suggest that you run the leads behind you so that persons or vehicles approaching from behind might be able to see that you are wired for sound. 
FINAL ADMIN
EVENT ETHOS: ‘RACING’ AND OUR FINISH TIMES SERVICE
Completing not competing. Rat Race’s ethos has always been about inspiring folk to undertake challenges in awesome outdoor locations. Patagonia Glacier to Glacier is just that, taken to an epic level. This is not a formal race environment and there are no winners and losers. We do not award prizes for the fastest folk. There will be no splits. Indeed, there will be no timings. Rat Race totally appreciate the incredible commitment of those taking on the challenges we lay down and each participant is as important as the next regardless of how fast you can cover the distance. This is akin far more to an expeditionary undertaking than anything else.
​
In delivering this unique challenge we prioritise factors such as safety, camaraderie and environmental concerns. Respecting the wishes of local stakeholders with our route management and litter policies is vital in being able to bring folk together for this unique experience. Safety above all else is paramount, as you will fully appreciate. To reasonably balance all these factors, we emphasise that the event is not a formal race environment, rather it is a challenge in the great outdoors where great folk come together with a common purpose.
​
TRANSFER DEADLINE
At the time of booking, on our website and within our welcome email we made clear that your purchase is non-refundable. But up until 12 weeks prior to departure, you could use our transfer system if you wished to withdraw from the event. We respectfully remind all participants that unforeseen circumstances preventing attendance is what travel insurance is designed for and is the reason for this as a strong recommendation on such undertakings.
​
We want to be really clear that the transfer option is there for you if you need it. But it does have a deadline. That deadline is  Friday 29th August 2025. This is 12 weeks prior to the event and our advertised standard transfer window for international events. After this time, we regret that we simply cannot change entries and if you are in, you’re in. So if you don’t think you’re in this time around, please do ensure you use that transfer window and get your transfers in by the dates above. You can do that by logging into your RR account, heading to the ‘Your Entries’ tab and hitting the ‘Transfer button’.
​
Please note event credit is except from the transfer process. Once credit is redeemed against an event entry it is locked into that event. You can read our transfer policy HERE ​
VIDEOS
If you have not seen them already, we have some glorious video edits that provide a handy guide to the first 5 day of activity!

​
LOCAL PAYMENTS
Card payments are widely taken across Argentina. In remote areas having some cash is always useful. US Dollars are preferred by most places. We would recommend a couple of hundred dollars in cash is likely sufficient.
​
When we are staying in hotels, you may charge incidentals to your room if the hotel has that facility. All room accounts should be settled prior to leaving the accommodation in each location. If hotel room bills remain unsettled Rat Race will reserve the right to charge your nominated card, plus a £20 admin charge per unpaid bill.
​
COMMS COVERAGE & DATA
Mobile phone signal is patchy and varied all across the event. El Calafate is generally very good. El Chalten is pretty weak. The trails and cycling routes are often signal less. Wifi is found in nearly all buildings and accommodation, except for the wild camp when there are no buildings!
​​
​The event will not be providing satellite data or phone services as standard unless for EMERGENCY USE via satellite phone.
​
​
CONTACT
To facilitate the very best support for you whilst embarked on the event, we have prepared some contact information below that should assist you and loved ones both before departure and then throughout your Event experience in Patagonia.
