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 with shared checkpoints and finish at Ashton Park School. The 45-mile race starts and finishes at Ashton Park School, while the 30-mile race begins at The White Horse, Hambrook.

The course includes four checkpoints offering food and drink, and runners must navigate the route themselves. Finishers receive bespoke medals and technical T-shirts. Completing both summer and winter 45-mile events in the same year earns runners a special GMU buckle. Visit the organization's website for the most recent information.
