Route description
Route description

This triathlon consists of a 400m swim, 20k bike, and 5k run.

Participants will race around flat closed roads and swim in clean, calm waters. All while being in the epic Olympic surroundings of Dorney Lake - one of Team GB's most successful venues.

The nature of this race makes it ideal for both professionals and first-timers alike.

Please note this is a non-drafting event, meaning it is against the rules to take shelter behind another competitor during the bike phase to gain a competitive advantage.
