About the Event

The Grafham Triathlon is a standout fixture on the UK triathlon calendar, held at the renowned Grafham Water reservoir—an elite venue that has hosted national championships and GB qualifiers. With both Standard and Sprint distances, as well as a Standard Aquabike option, it caters to competitive athletes and newcomers alike. The race begins with a swim in the clean, calm reservoir waters, followed by a fast, flat bike ride through Cambridgeshire villages and a scenic run on gravel trails that cross the impressive Grafham dam wall. Expect a lively atmosphere at the transition zone and finish line, with spectators lining the trail and plenty of vocal encouragement. From first-timers to seasoned triathletes chasing a PB, the event’s professional organization and spectacular setting deliver a high-quality experience from start to finish.
