Forest of Dean Ultra Marathon 55 km
The Forest of Dean Ultra Marathon is a circular 55 km trail race through the Forest of Dean, scheduled for 10 October 2026. The route combines technical single track, wide open stretches by the River Wye, ridges with open views, fields and woodland vistas that reach toward the Brecon Beacons. The precise course changes year on year and is navigated using a GPX file provided to participants.
Navigation is self managed and following the GPX file is a requirement. Competitors must carry mandatory equipment at all times, including a GPX file on phone or watch, charging backup, a waterproof jacket, basic first aid, a hydration system and a head torch. The route includes long gaps between checkpoints, with around 15 km between some aid stations.
Race headquarters and parking are at Beechenhurst in the Forest of Dean. The event provides a minimum of three stocked aid stations with toilets, water, food, snacks and electrolytes, plus parking for support vehicles. There is an open cafe presence at Beechenhurst, Symonds Yat and Mallards Pike. The event offers professional timing, free race photos, finishers medal and event merchandise. Support vehicles, qualified race and medical professionals are available on course. Canicross entries are permitted and form a separate race category. The course has a 10 hour completion limit and top finishers may be asked to submit GPX files for verification. Visit the organization's website for the most recent information.
