Dorney Triathlon - June

Dorney Triathlon - June takes place at Dorney Lake on 6 June 2026 and offers Super Sprint, Sprint and Standard distances alongside Aquabike and relay options. The race uses the purpose-built Dorney rowing lake and enclosed grounds, providing clear water for the swim and a flat, fast bike and run course that is well suited to chip-timed personal bests. The event is chip timed and run within an event village environment with marshals and on-course support to guide competitors from start to finish.

The organiser notes that some entries require British Triathlon membership or a single-use Race Pass and that the event is draft illegal. Wetsuit hire is available via Zone3 (and third-party hire options are linked from the event page) and free parking is provided at the venue. Multiple morning wave starts are used to manage Sprint and Standard fields and the schedule includes a later Super Sprint wave, making the day suitable for a range of abilities and team relay entries.
