The Winter Gmu

The Winter GMU is an ultra marathon event held in Bristol, offering two race distances: 30 miles and 45 miles. Both courses follow a loop around the Community Forest Path, with the winter edition characterized by muddy and challenging conditions, and the summer version being faster and firmer. The event features four checkpoints with food, drink, and amenities, and includes chip timing and optional pacers.

Participants receive bespoke medals and technical T-shirts upon completion. The race emphasizes self-navigation, mandatory gear, and adherence to safety rules. It supports wildlife conservation through charity entries for the Avon Wildlife Trust, and offers various registration options, including team and charity places.
