The One on The River - Henley takes place across the scenic Thames Valley area with its routes going through Culden Faw Estate.
Swim the river, cycle the hilly open roads, or run through the trail paths enjoying the views of Henley-on-Thames and the surrounding areas. Join the Triathlon for the ultimate challenge, or either of our Duathlon/Aquabike/Aquathlon categories if you prefer to focus on specific disciplines. If you only fancy a dip in the Thames, then pick one of our swim-only categories instead and get yourself wet! With multiple distances for each discipline, you’ll find something to challenge yourself this September.
