JOIN ATW, THE LARGEST MULTISPORT ORGANISER IN THE UK, AT THE ICONIC GRAFHAM WATER FOR OUR SPRINT & STANDARD DUATHLON ON SUNDAY 26TH OCTOBER 2025.
Whether you are an experienced athlete looking for a fast race, trying to qualify for the GB team, or simply a novice competitor looking for a safe and friendly venue, Grafham Water is ideal for all!
We guarantee you’ll enjoy this fantastic venue that has been used for multiple award-winning events, national championships and GB qualifier races.
Standard Duathlon - run 10km, cycle 38km, run 5km
Sprint Duathlon - run 5km, cycle 17km, run 2.5km
The run is a 5k lap course using the natural footpaths of Grafham water that head out and back across the iconic dam wall before looping past the finish area where you’ll receive great support (the second run of the Sprint event will turn near the start of the dam making a 2.5km lap). The bike is an out and back ride to St Neots with minimal turns allowing for lightening-quick riding. The Sprint distance will turn back in the village of Perry.
These events are draft-illegal, and there will be British Triathlon Motor Officials on the course to ensure that the racing is fair and safe.
ATW was established in 2011 by James Shipley. We have now become a national events company in the UK, specialising in Running, Triathlon, Duathlon, Aquathon, Cycling, Swimming and all permutation of swim-bike run events. With over 40,000 entries a year ATW has become a firm favourite amongst people who are determined to Dream, Believe and Achieve.
