Coming in 2019 – The GMU in March is being re-branded The Winter GMU and we are adding another permanent race to the calendar – the Autumn GMU in September. Completion of both events in the same year will entitle you to the GMU Buckle – and it doesn’t stop there! There will be a series of four buckles available, dependent on you accumulative finishing time. The March event is always guaranteed to provide muddy and wet conditions, and the Autumn event should be much drier and faster. To add to the experience, the September event will be run in reverse!
