Other questions
The race takes place on Saturday 21 November 2026.
Yes, it is a UTMB World Series index race.
Our North Chilterns event is undulating throughout, with a few sharper hill climbs scattered throughout. The route is similar to our Chiltern Ridge 50K, however due to the autumn date it is likely the ground conditions may be softer and more challenging.
No, there are no qualifying standards required to enter this race.
Our route will be marked throughout with orange signage/ribbons, along with marshals at several key points. Course checkers will be out during the race ensuring that signage remains in place. We ask runners to make sure they have access to the route via a phone or watch, to act as a backup in an emergency.
