ATW Grafman Middle Distance Triathlon

About this event

Grafham Water hosts this well-established middle-distance triathlon, a staple of the UK triathlon calendar that's been running for years. The course features a 1.9km swim in the reservoir with a distinctive mid-swim beach exit, followed by 90km of cycling through quiet Cambridgeshire lanes, and finishing with a 21km run offering views across the water to the iconic Valve Tower. The event caters to experienced triathletes looking for a solid challenge on a tried-and-tested course. An aquabike option is available for those who prefer to finish after the bike leg. With its combination of open water swimming, rural roads, and lakeside trails, it's a classic British triathlon venue that keeps athletes coming back.
