Dorney Lake Triathlon

The Dorney Lake Triathlon takes place at an Olympic venue in Windsor. The event features a purpose-built lake for open water swimming and a flat, traffic-free course for the cycling and running segments. Participants navigate the bike and run sections on wide roads and paths situated beside the lake.

The event offers several race formats and distances to accommodate different preferences. Athletes can choose from the following multisport options:

  • Super Sprint Triathlon: 400m swim, 9.5km bike (2 laps), and 2.5km run.
  • Sprint Triathlon: 750m swim, 19km bike (4 laps), and 5km run.
  • Standard Triathlon: 1500m swim, 38km bike (8 laps), and 10km run.
  • Aquabike: Available for both Sprint and Standard distances, focusing on the swim and bike legs.
  • Relay: Options for teams to complete the Sprint or Standard distances together.

The course is designed for accurate pacing with chip-timed results provided for all competitors. The venue includes an event village with various food and drink options. Participants receive a unique themed medal, free race photos, and post-race refreshments at the finish line. Marshals are positioned throughout the course to provide guidance and wayfinding.

This is a partner event where RunThrough memberships are accepted for entry until the event reaches capacity. The terrain is entirely road-based with minimal elevation changes, ranging from 20m for the Super Sprint to 80m for the Standard distance.
