The Rat Race team are here to help you go the distance and support you to this bucket list finish line, no matter your pace or background.
tarting beneath the breathtaking silhouette of Bamburgh Castle, and finishing in the historic heart of Edinburgh, this fully supported adventure is a coast-to-city journey like no other. Along the way, you’ll cross ancient paths, rolling coastlines, wild moorland and peaceful villages as you tick off a truly iconic ultra-distance.
But this isn’t just about distance, it’s about doing things differently. At Rat Race, we believe in making big adventures accessible. That’s why this route is waymarked, fully supported, and set at a pace that allows everyone to take part. There are no strict cut-offs. No pressure. Just a commitment to get you to the finish line, whatever your pace.

A really great park, fab shower and amenity block. We are new to the motorhome scene and this site has strengthened our commitment to our new freedom Thank you for a great site!!!
Superb place and facility. I’ve never been to Northumberland, and now will be returning back for the third time in 9 months (even though you are 360 miles away from me).
Even in October for our last stay we found the park to be in superb condition. A great tribute to the hard working park staff which was much appreciated. We look forward to returning.
Exceptionally clean shower block and very helpful friendly staff.
Absolutely lovely campsite, great atmosphere, felt really welcomed. Amazing views and great distance from local tourist attractions, will definitely be returning soon!
We have stayed at this park many times and always return it’s a lovely clean well maintained park with super layout in the touring field for the kids playing on the field/park. Family shower rooms really really good and clean. We have also stayed at the other 3 parks you have but Waren is our favourite for a close to home weekend away! Thanks.
Thank-you very much for an enjoyable stay. It has been my favourite camping trip. I loved the adult only camp area. Highly recommended to friends.
We hired your BBQ hut and what a fab idea it was! Kids loved it, it was a fab little experience.
We stayed for 2 nights in a tent. Our children loved it! They loved the parks, the outdoor pools, football pitches and large grassed areas throughout to play games.
We have travelled all over the UK in our motor home. Waren Mill was one of the first sites we stayed at and has remained our favourite!
Our daughter loves coming to Warren mill and has great fun. The staff are always helpful and friendly and we’ve made lots of great memories and look forward to making lots more soon.
We love Waren, it is one of our favourite sites. We feel so at home there. It was the first ever site we went to, for our first trip out in our first touring caravan, for our daughter’s second birthday celebrations. It is a tradition now that we go every year for her birthday, and have just done it for the third year running. We love it so much. And long may it continue. Cant wait to try the sister sites, as she gets older. Brilliant site, lovely atmosphere, keep up the good work guys! Thankyou x
