Wendover Woods Marathon, Half Marathon & 10K 2026

The Wendover Woods Marathon, Half Marathon & 10k is a multi-terrain running event held within Wendover Woods, Buckinghamshire, part of the Chiltern Hills. This event is included in the Autumn Festival of Running and features a marathon, half marathon, 10k, and a junior run. Participants can select a distance ranging from a short forest race to a full marathon. The course has hills and includes significant ascents, with a six-hour time limit for all participants. The 10k race follows a multi-lap course on forest trails. The longer races extend this challenge across similar rolling woodland terrain. This event is suitable for novice trail runners, experienced runners seeking a hilly challenge, and marathon runners desiring a more demanding course than a flat road race. It welcomes pets, and the venue is family-friendly, offering an on-site cafe, Go Ape, adventure play areas, biking trails, and a nearby Gruffalo trail for children.
