Dorney Lake Evening Triathlon

The Dorney Lake Evening Triathlon takes place at a purpose-built Olympic venue in Windsor. This event features multiple multisport options conducted on a flat course, including a lake swim followed by cycling and running on the surrounding grounds. Participants can choose between different formats held on a road and water terrain:

  • Super Sprint Triathlon: Includes a 400m swim, a 9.5km bike leg consisting of two laps with 20m elevation, and a 2.5km run.
  • Sprint Triathlon: Consists of a 750m swim, a 19km bike leg over four laps with 40m elevation, and a 5km run totaling two laps with 6m elevation.
  • Sprint Aquabike: A swim-bike option featuring a 750m swim and a 20km bike ride.

Each discipline is marked with distance flags, and the event utilizes chip timing for results. The course is designed to be flat, providing a consistent surface for those seeking specific performance targets.

The event includes an organized village area with various food and drink options. All participants receive a themed medal, free race photos, and post-race goods upon completion. This edition of the event is held in support of Macmillan Cancer Support. Visit the organization's website for the most recent information.
