ATW Odyssey Triathlon

Back for another unforgettable year, the ATW Odyssey Triathlon delivers a full-scale endurance experience through swim, bike, and run across the beautiful Cambridgeshire countryside. Building on the success of the Odyssey Aquabike, 2025 introduces a brand new Half Distance Triathlon, giving athletes more choice while preserving the same spectacular atmosphere. Participants can choose between the Full Odyssey Triathlon, which includes a 3.8km swim in the meandering River Ouse, a 180km bike ride through rural Cambridgeshire, and a 42.2km run around the riverside town of St Neots, or the Half Odyssey Triathlon, a 1.9km swim, 90km cycle, and 21.1km run around scenic St Neots. Held alongside the Odyssey Aquabike, the triathlon offers both camaraderie and competition, welcoming athletes of all abilities to take on their own personal Odyssey in a safe, well-supported environment.
