ATW Grafham Triathlon

ATW Grafham Triathlon, organized by Active Training World, is held at Grafham Water, Grafham, Huntingdon, Cambridgeshire. The event offers Standard (1500m swim, 38km bike, 10km run) and Sprint (750m swim, 17km bike, 5km run) distances, ideal for both seasoned athletes and first‑timers in a safe, friendly venue. The swim takes place in the clear Grafham Water reservoir with a 750m loop; the flat bike course is out-and-back through scenic villages (Sprint turns in Perry; Standard in St Neots); the run is a flat 5k lap around the reservoir, finishing near the transition area with good supporter presence.

Extras include Aquabike and relay options, Zone3 wetsuit hire, pre-event accommodation, free photos, well‑marked courses, marshals, a charity partner, and finish-line goodies. Visit the organization's website for the most recent information.
