The One on the River - Henley
The One on the River - Henley takes place on Sunday 8 August 2027 in Henley-on-Thames, Oxfordshire, with the River Thames at the heart of the event. The event village is located close to the river and the programme includes an open-water swim course.
The event offers a choice of triathlon, duathlon, aquabike, aquathlon and standalone open-water swim options, with multiple distances available across the disciplines. Swim, bike and run courses are clearly marked and supported by marshals; the number of laps and exact course details depend on the chosen discipline and distance.
Event facilities include chip timing, race photography, a finisher's medal and medical support. Race packs and timing equipment are collected at the Registration Tent on race morning and are not posted. Packs may include a timing chip, race number, bike and helmet stickers and a swim hat. Transition arrangements and final course details will be provided to registered participants before race day.
Participants in disciplines covered by British Triathlon rules may require British Triathlon membership or a Race Pass; full requirements are confirmed during registration. Final start details, registration instructions and other race-day information are sent to registered participants ahead of the event.
