The Summer GMU

The Summer Green Man Ultra (GMU) is a challenging ultra marathon held near Bristol, UK, featuring two race distances: a 45-mile full loop and a 30-mile partial loop of the Community Forest Path. Both races run clockwise on the same day, starting and finishing at Ashton Park School (45-mile) or The White Horse, Hambrook (30-mile). The course includes four checkpoints offering food and drink, with a total ascent of approximately 945 meters.

The event emphasizes self-navigation, with GPX files and timelords available to assist runners. Finishers receive bespoke medals and technical T-shirts, and top performers earn trophies and free entry for the next year. The race supports Avon Wildlife Trust charity and promotes environmental care along the route. Visit the organization's website for the most recent information.
