You should have all had an e-mail with instructions…
But just incase here is what you need to know!
If you have never done the Challenge before we hope you will enjoy your day. It is not your usual Trail event. We aim to run a relaxed fun day, there are no strict start times, again, please see the Event Day Page for suggested start times, it is up to you to work out the best time for you to start based on how fast you think you’ll run/walk/limp/crawl. We will have very fast 50k runners who will start early and be through CPs before they are open.
Please Check the Event Day page on the website and read it fully. This is where updates will be posted between now and Sunday, along with the Facebook group and page. The routes have been thoroughly checked but we cannot control the weather. Please be careful and if front runners can, please use the emergency number 07753 581541 to let us know of any major issues with the course or report at the next check point.
The event is self guided! There are no course markers!
All the route descriptions and GPX files are available via the website. PLEASE NOTE some FOOTPATHS have been CLOSED since 2025. You must use up-to-date descriptions and GPX files.
We provide NO paper copies of the route description or any maps, you must print them off and bring them with you. Links to the maps are included below, these are not on the website! HINT: Turn right out of the school. If you have a 50K map we will clarify the Datchworth loop on Sunday.
The course has been walked and all descriptions have been updated as there were MAJOR CHANGES in 2024. All routes now pass through Aston and not Benington. 💙🩵
