Event overview
The Dorney Duathlon takes place on 4 April 2026 at Dorney Lake, Court Lane, Windsor SL4 6FJ. The event is organised by Active Training World and is described as draft-illegal. The venue offers flat, scenic grounds that lend themselves to a totally flat bike and run course, noted as suitable for chip-timed personal bests. The run course will be marked with distance flags. Helpers will be present on both the run and bike courses. Spectator facilities include a balcony cafe overlooking the transition area and a multi-lap layout that allows repeated viewing of competitors. Free parking is available.
