Event Overview

The Dorney Triathlon takes place at the Dorney Lake Olympic rowing venue in Windsor. This site features a crystal clear lake and flat, scenic grounds designed for high-performance sports. The event is designated as draft illegal, meaning participants must maintain specified distances during the cycling leg.

The course is widely recognized for its flat topography, including both the bike and run sections. This environment is conducive to achieving personal best times through chip timing. The venue provides free parking for participants and spectators, and the site includes catering vendors for attendees.

Race Categories

Participants can choose from several multisport formats across various distances:

  • Super Sprint: 400m swim, 10km bike, and 2.5km run.
  • Sprint: 750m swim, 20km bike, and 5km run.
  • Standard: 1500m swim, 40km bike, and 10km run.
  • Aquabike: Available in Sprint and Standard distances, consisting only of the swim and bike legs.
  • Relay: Options for teams of 2 or 3 individuals to share the three disciplines.

Participation Requirements

All competitors must hold a British Triathlon race licence. This can be obtained through an annual membership or by purchasing a single-use Race Pass. Age requirements vary by distance: the Super Sprint and Sprint events are open to those aged 15 and over, while the Standard distance requires participants to be at least 17 years old by the end of the calendar year. Wetsuit hire is available on-site through designated providers for those who require equipment. Visit the organization's website for the most recent information.
