THE EDGE - Wendover Woods

THE EDGE is a timed trail event organised by Underground Run Club at Wendover Woods, Aylesbury (HP22 5NQ). The format gives participants nine hours to complete as many laps as they can on a marked trail course.

Each lap is 6 km with approximately 150 m of elevation gain. Competitors receive the course file before the event so they can load the route onto a phone or watch. The core rule of the event requires every completed lap to be faster than the one before; if a lap time does not improve on a previous lap, the competitor’s race ends.

The event is permitted by Forestry England. On-course support includes a well-stocked aid station, race photography, and assistance from the event team and volunteers. Entries include a bespoke medal. Ticket prices on the listing range from £65 to £67. The organiser’s published policy states there are no refunds.

The event emphasises pacing and repeated efforts over a single continuous distance. The marked course and downloadable map aim to help competitors plan their lap strategy and pacing across the nine hour window. Visit the organization's website for the most recent information.
