The Grafham Water Trail Races take place at Marlow Park, offering 10K and Half Marathon distances on scenic trails around Grafham Water in Cambridgeshire.
Both routes are fully marked and marshalled, following a mix of tracks, bridleways and countryside paths. The 10K provides an accessible introduction to trail running, while the Half Marathon extends into a larger loop around the reservoir, offering a more challenging experience with varied terrain and open views.
The course takes in sections of the Three Shires Way, with wide runnable trails and steady terrain throughout. The setting provides a combination of lakeside scenery and quiet countryside, making it an enjoyable route for runners of all abilities.
Runners benefit from a well organised event with water stations on course, first aid support and a fully managed route. All finishers receive a medal, with prizes awarded to leading runners.
A welcoming and well supported trail event that combines accessible distances with scenic surroundings and a strong community atmosphere.
