MORE INFORMATION:
You can take this beautiful coast to coast adventure over one or two days. The one-day option is suited for those who want to go hard and test themselves over this rugged terrain. The two-day option is very achievable for people who are looking for the perfect adventure weekend.
The one-day challenge is a mammoth undertaking. Especially if the prevailing wind tries to blow you back to the start line. Bike selection and your nutrition plan are very important to give you the best chance of completion. Our cut-offs are fixed, and you will be taking on a very challenging mountain run after a draining coast to coast cycle ride. Successful finishing times on the one-day challenge range from 8 hours in calm conditions to 14 hours in heavy weather.

The nature of an adventure is that sometimes, the uncertain becomes certain! 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 ned to wheel put 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!
Click ‘Buy Event Voucher’ and go through the sign-up process, you’ll then be issued with an event voucher which will automatically reserve you a place in the event you have chosen.
Rat Race require you to be over 18 on the day of Registration for this adventure. If you wish to participate as a family group or with a responsible adult and you are 16+, we will consider applications on an individual basis. Please contact us if this is the case.
Getting to the start line is important and we are there to help you as best we can. However, if you feel on reflection that it is just not your time yet, we do have a transfer system that you can use to transfer out, receive Rat Race credit and come back again next year or do something else. Credit is typically valid for 12 months and there is a fee to be paid for transferring out in this way. We want to be really clear that this option is there for you if you need it, but it does have a deadline. View our full terms and conditions here.
The latest kit list will be sent to you before the event within the Essential Event Information Document.
Of course. If you run for Children with Cancer UK and raise the target amount for this event per person, we will refund your entry fee up to the amount of £450. You are of course more than welcome to fundraise for any cause close to your heart. Click here to find out more.
Yes, you can. We welcome support on almost all of our events and if you do decide you want to come and work with us, we will make sure we look after you. Click here to find out more about volunteering for Rat Race.
We’ve put together a fantastic new instalment plan that allows you to choose how many months you want to spread the cost of this brilliant adventure over. You can pay it off all in one go or spread it over as many months as you like, totally interest free. There is no credit check required to use this facility. When you sign up to the instalment plan Rat Race will then set up a reoccurring payment and your card will be debited on the same date each month. If there is an error with your payment you will receive reminders from Stripe, our payment provider, and also the Rat Race customer service team. After 3 attempts to contact you if the outstanding balance remains unpaid we will assume you wish to cancel your entry and will withdraw you from the event and you will not be eligible to enter our transfer process and no monies will be refunded.
Add Refund Protect to your booking during purchase and receive a full refund of your entry fee if you are unable to attend the event due to a qualifying unforeseen circumstance. PLEASE NOTE this protection is with our 3rd party partner Refund Protect and NOT Rat Race. In the event you make a refund application this is administered by the Refund Protect customer service team, Rat Race are not privy to the application and cannot intervene on your behalf to influence the outcome determined by their team.
To check the full list of qualifying unforeseen circumstances that are protected please click here to view Refund Protect terms and conditions.
To add Refund Protect (administered by a 3rd party) to your Rat Race booking simply select this option when presented during the entry process. Refund Protect cannot be added retrospectively. Rat Race will then send you name and booking details to Refund Protect in order to protect your transaction with them. If you opt to pay in instalments and transfer your entry before the entry cost is full paid you will be liable to ensure the cost of Refund Protect has been fully covered. This total amount will be deducted from any Rat Race credit due through the transfer process or you will be invoiced by Rat Race for the outstanding amount as Rat Race have paid this on your behalf to Refund Protect at point of entry.
By entering this event you agreed that you have entered in your own name (not nickname) and will bring photographic ID to event registration to prove your identity. If you cannot prove your identity at that time then you won’t be able to complete registration and therefore won’t be able to take part.
No unfortunately we cannot accommodate dogs on the route or in the campsite.
If you choose to take a spare pair of shoes you will need to carry them with you in your rucksack. The only exceptions are at Cawdor Castle where you can leave your cycling shoes attached to your bike (when dropping off your bike before the start of the event) and Fort William transition when you will be able to leave your cycling shoes ATTACHED to your bike or in the bag we provide to you at registration (for us to transport). We will not take any items to the Fort William transition for you.
Cut-Offs are an important part of our Event Management Plan and Risk Assessment and are based on the time of sunset. Participants venturing onto the hill or on to the water after our cut-off times likely be finishing in the dark, and as we do not specify mandatory equipment or provide safety provision for that scenario we will enforce the Cut-Offs as described. Cut-off times are applied to your departure from these locations and not your arrival.
Cut offs for those taking it on in 1 day:
Fort William 1600
Kayak Stage 1930
Course closes 2000
Cut off for those taking it on in 2 days:
No cut offs on day 1
Day 2
Fort William 1430
Kayak Stage 1800
Course closes 1900
If you fail to make the cut-off you will be transported forward to the finish only.
The Kayak cut-off at Lochlevan is flexible in both directions depending on the visibility and wind conditions on the day. If conditions become too rough for kayaking, the run route will redirect you to finish at Kinlochleven where we will bus you to the finish line.
Trek/Run – 7 miles
Road Cycle – 44 miles
Off Road Cycle – 20 miles
Road Cycle – 14 miles
Trek/Run – 14 miles
Flat Water Kayak – 1 mile
*Please note that distance are variable depending upon weather conditions and route access.
Coast to Coast is a tough event. You’ll be taking on a hilly journey that is heavily impacted by weather conditions. You’ll be running, kayaking and, more importantly, cycling into the prevailing wind, so the chances are you’ll find the riding sections tougher than your usual ride out. That being said, when the sun shines, you will see the most fantastic views imaginable!
The average finishing time for one-day participants is 12 hours, and it’s 14 (over two days) for the two-day participants. To make this coast to coast journey, you need to be fit and able to keep your energy levels up with a solid nutrition plan. If you put in some training time and arrive kitted out and prepared, then this challenge is achievable, but it should not be underestimated
Whether you are entering the 2-Day or 1-Day category, you will use the same bike throughout this coast to coast event. The perfect bike for this event's coast to coast cycle portion is either a cyclocross bike. a hybrid bike or a gravel bike. You can complete it on a mountain bike, and for 2-day participants, this is a viable option, but 1-day participants will struggle to get through the road riding miles within the cut-offs. Road bikes are not recommended for this coast to coast cycle route, although they would be possible to use if you add appropriate tyres, good pressures and a dose of skill.
You can hire a bike from our partner Cycle Hire Scotland. The link to book can be found on the EXTRAS tab below. Bike hire is limited so please book early to avoid disappointment. Helmets and spd style pedals are also available to rent, or you can bring your own of course.
No. We will provide the kayaks which are sit on tops and stable. We also provide water safety from local professionals. Please note that kayaking is done in pairs, though those at the front of the field can go solo if they arrive alone.
Yes, you do need to provide your own bike. You can bring your own, hire one locally to you and bring it along, or arrange hire from our hire provider.
You can hire a bike from our partner Cycle Hire Scotland subject to availability.

"This was my first adventure race! It was an amazing experience that made me want to do more as I loved it!"
I felt safe and reassured pre event thanks to the emails, the website, the very quick answers to my emails when I had questions and during the event thanks to all the marshalls, signs along the way, etc. I also really enjoyed it and felt relaxed because it did feel fairly easy compared to what I was expecting (I was prepared for much harder conditions as it was in Scotland but we had beautiful weather and no strong head wind on the bike!)

IT WAS A WEEKEND THAT I WILL NEVER FORGET AND AM PROUD TO HAVE COMPLETED
I managed to just about scrape through the initial run and cycling stint based purely on being an avid commuter cyclist and doing a couple of 5k road runs per week. This was not enough to tame this beast of a route ...
