Dorney Lake Triathlon
The Dorney Lake Evening Triathlon, held on August 27, 2025, takes place at the Olympic venue of Dorney Lake in Windsor, UK. Participants can choose from Super Sprint, Sprint, or Aquabike (swim-bike) distances, featuring a 400m or 750m swim in the purpose-built lake, followed by flat, fast 10km or 20km bike courses and 2.5km or 5km runs on flat terrain. The event offers chip timing, official photos, and unique themed medals.
The flat course and clear distance markings make it ideal for personal bests, with plenty of support to encourage athletes throughout the race. Visit the organization's website for the most recent information.
Always double-check with the organizer's website – things can change, and we might have sprinted past a few details!
