Rat Race – Coast to Coast route


Traversing forest, trails and lakes, competitors should underestimate that physical test this event represents. This is an extremely hilly route, often entirely at the mercy of weather conditions - especially what can be relatively high winds.

This event takes place on ‘Live’ public roads, private roads, and shared access trails. There are no closed roads. Always exercise caution.

Average finishing times is 12 hours on the one day Expert, and 14 on the Challenge, split over the 2 days. A good level of fitness is absolutely necessary for this, as is a decent nutrition strategy to keep you going throughout. The route will be clearly signed, with professional safety teams operating throughout. With the the right planning, the route is more than achievable.


Do not receive support from friends & family spectating en route. You may use the public facilities immediately en route but do not deviate from the route to seek these. Come prepared.

Bike Transition Areas will be fenced, and you will be able to get your bike out ONLY if you have your security wristband attached to your wrist.

We will provide you with a safety procedure to follow in case of emergency.

Dogs are not allowed at Challenger Fort Augustus Campsite unless they are on a lead, cleaned up after, and do not disturb participants sleep.

We recommend that participants have insurance to cover damage, loss, theft, injury and non-attendance. Rat Race accepts no responsibility for the loss of, theft, or damage to any Participant property or the circumstances of Participant non-attendance.

Not for the faint hearted. 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 mandatory kit is key. You will be taking on a very challenging mountain run after a draining cycle ride, not to mention the kayaking. Successful finishing times on the one Day Expert class range from 8 hours 19 minutes in calm conditions to 13 hours 32 minutes in heavy weather.


Most participants take on the Coast to Coast challenge over two days and join us overnight to camp at Fort Augustus. Breaking up the challenge makes this more achievable and allows you to enjoy a cracking weekend out with some mates. Don’t forget to get your camping passes in advance of the event, which you can buy here.

THE FINISH - The Isles of Glencoe Hotel

The finish for the event is on the lawn of the hotel so grabbing a room here is the perfect way to finish the event for many of you coast to coasters. Booking of rooms is directly with the hotel. This allows the hotel to concentrate on your accommodation needs while Rat Race focus on helping you get there by foot, bike and kayak. Please contact the hotel directly on 01764 651843 to secure your room. You will need to know the username you created when entering the event. This is to ensure the hotel is kept just for event entrants.

    Did the 105 Miles in 2017

    I completed this event in 2017, choosing the 'Expert' category to do it in one day. I definitely wasn't an 'expert' at the time, and this was some of my first proper trail running experience. I was initially sceptical about the high cost of entry, however, having done it, the organisation from Rat Race was fantastic and it is a very logistically-difficult set up, so I think they did a great job, and made it very seamless experience as competitors. We had shuttles to and from registration on the Friday, bag transport throughout the race, and bike transportation arranged, as well as very well stocked checkpoints. It is a really exciting and interesting format - one 'easy-ish' trail run of ~11km, then a long cycle (think ~130km?), a more serious trail run over proper highland terrain ~24km and then finally an absolutely stunning kayak section. The cycle is about 3/4 on road, and 1/4 on trail in the latter part. I chose to cycle with my roadbike with more grippy and puncture-proof tyres, and this worked really well. I think I had enough control off-road and was comfortable enough, but obviously enjoyed the faster and lighter bike on the road! The cycling route is also quite forgiving despite the length, and there was only one serious climb on this section. The running (especially last trail run) was more difficult, but the scenery was absolutely stunning.
    We chose to stay at the hotel right on the finish line, and there were some good deals via Rat Race to get dinner & a room there. It was very handy to be able to store our bikes in their bike parking area by the hotel overnight, and they organised a coach transfer back to Inverness the next day.
    In summary: Would very much recommend, and well worth the money! If you can, arrive a few days early or stay after, as both the town at the start (Nairn) and the finish (Ballachulish) are really beautiful.
