Set at the spectacular, flat, and smooth-surfaced Dorney Lake near Windsor, this event takes you around the perimeter of the iconic water.
The legendary Eton Dorney – as Dorney Lake was known during London 2012 – held 30 events throughout the Olympics, with Team GB taking a total of 12 medals. Soak up the atmosphere and invoke their heroics to inspire you to a new PB!
The Dorney Lake course is nestled amongst 450 acres of glorious parkland – including an Arboretum and Nature Conservation area – whilst being just a few miles from Windsor and a short drive from Heathrow airport and West London.

The running categories are expected to be licensed with UK Athletics (UKA) and the results published by Run Britain shortly after the event.
The multisport categories (excluding the swim) are draft-illegal (TT bikes permitted) and are expected to be licensed with the British Triathlon Federation (BTF), the competition rules of which can be found here. We recommend participants familiarise themselves with the information therein, specifically sections 4 (Swimming), 5 (Cycling), 6 (Running) & 7 (Transition) for details on equipment and their expected conduct during the event. Entry includes day membership for non-BTF members which will be provided on event day.
Bib numbers (and bike stickers/swimming caps where applicable) are available for collection at the event only, participants should not expect to receive anything by mail.
Results will be uploaded live to our website (internet connection permitting) and communicated to all pre-registered participants within 24 hours of each event.
All finishers will receive a medal on completing their event and, subject to a competitive field of participants, prizes may be available for the top three places overall – and the top place in each of the veteran categories (V40/V50/V60/V70) – for both females and males at each distance. Winners will be notified via email by the end of the following week once results are considered final.
