About the Event

Challenge yourself with the Grafham Water Duathlon, hosted by one of the UK's premier multisport organizers. This dynamic race caters to athletes at all levels—from those seeking personal bests and GB team qualifications to newcomers looking for an encouraging start.
Competitors can choose between two thrilling distances: the Standard Duathlon (10km run, 38km bike ride, followed by a 5km run) or the Sprint Duathlon (a shorter 5km run, 17km cycle, and concluding with a 2.5km run). Both courses offer unique terrain that showcases Grafham Water's picturesque surroundings.
The running portion of both events includes scenic laps along natural footpaths bordering the water’s edge, featuring an exhilarating stretch across the dam wall for added adrenaline. The final loop brings runners past the finish line where they can soak up the support from cheering spectators.
For cyclists, the race offers a fast and straightforward out-and-back course to St Neots with minimal turns, allowing participants to focus on speed and efficiency. Sprint duathletes will turn around in Perry before heading back towards Grafham Water for their final run segment.
This event is held at Grafham Water, known as one of Britain’s top multisport venues due to its hosting of national championships and GB qualifier races. The atmosphere here is electric with a strong sense of community among competitors striving for excellence.
Whether you're aiming high or taking your first steps in the world of duathlons, this race promises an unforgettable experience amidst stunning natural beauty and supportive camaraderie.
Join us at Grafham Water to test your limits on one of Britain’s premier multisport courses.
