ATW Grafham Triathlon

The ATW Grafham Triathlon, hosted at Grafham Water Visitor Centre in Huntingdon, Cambridgeshire, offers both Standard and Sprint distance races. The Standard distance includes a 1500m swim, 38km bike, and 10km run, while the Sprint features a 750m swim, 17km bike, and 5km run. The swim takes place in the clean waters of Grafham Water reservoir with laps of a 750m loop.

The flat bike course passes through scenic villages, and the run follows natural footpaths around the reservoir, including crossing the iconic dam wall. The event also offers Aquabike and relay options, with a friendly atmosphere, well-marked courses, supportive marshals, and free event photos.
