ATW Grafman Middle Distance Triathlon
The ATW Grafman Middle Distance Triathlon takes place at Grafham Water Visitor Centre, Marlow Park, Grafham, Huntingdon, Cambs, PE28 0BH. The event offers three race formats: a middle distance triathlon, an aquabike, and a middle distance relay.
Race distances:
- 1.9 km open water swim with an Aussie-style exit halfway
- 90 km scenic bike course on quiet country lanes; non-drafting rules apply
- 21 km lakeside run passing the Valve Tower
The event has an overall cut-off time of 9 hours 30 minutes. Participants find marked routes, hydration and nutrition stations around the course, and marshals positioned on-course. Every finisher receives a bespoke Grafman medal and finish-line snacks.
Event services include an evening before registration option and on-site morning registration and transition opening. Camping is available nearby at Lakeview Paddock. Zone3 wetsuit hire is offered with day, weekend and monthly options.
