Event overview
Dorney Lake Events provides you with an opportunity to race like an elite around this unique and inspiring Olympic venue, in a draft-legal Sprint Triathlon, with the additional opportunity to qualify to represent Great Britain in the Age Group Sprint Triathlon World Championships in 2026.
The crystal clear lake and flat, scenic grounds lend themselves to a safe course for fast, draft-legal racing.
This 'draft-legal' Sprint Distance event will take place after the 'non-drafting' Triathlon in the morning has finished.
Please note that the race will follow British Triathlon 'draft-legal' rules and all bikes must comply with 'draft-legal' guidelines (eg drop-handlebars, no tribars, and UCI compliant wheels).
