Event overview
Join in at the Grafham Triathlon, brought to you by the largest triathlon organiser in the UK!
Whether you are an experienced athlete looking for a fast race, or a novice competitor looking for a safe and friendly venue for your first open water multisport event, Grafham Water is ideal.
Athletes of all levels are guaranteed to enjoy this fantastic venue that has been used for award-winning triathlons, national championships and GB qualifier races!
There are a choice of distances for you to tackle.
The swim takes place in the beautiful clean waters of the Grafham Water reservoir, with laps of a 750m loop. The Sprint race completes one lap, while the Standard completes two. The bike is a flat out-and-back bike course that takes you through some of the most scenic villages in the area. The Sprint distance turns in the village of Perry, while the Standard turns in the town of St Neots.
The run uses laps of a 5K route around the natural footpaths of Grafham water. The flat route heads out and back across the iconic dam wall before looping past the finish and transition area where you’ll receive great support each lap. The Sprint will head in to the finish after one lap, while the Standard completes two laps.
Anyone who doesn't want to take part in the run, there is a standard distance Aquabike (swim-bike) option and for those who would like to compete as a team, there is a standard distance relay option, with 2 or 3 individuals sharing the disciplines between them.
