Dorney Lake Duathlon - December

The Dorney Lake Duathlon is a run-bike-run event held in December at Dorney Lake, which served as the Olympic rowing venue near Windsor, UK. Participants can choose from Super Sprint, Sprint, and Standard duathlon distances. The Super Sprint consists of a 2.5 km run, a 9.5 km bike course completed over two laps, and a final 2.5 km run. This is a draft-illegal race, meaning cyclists must not form pelotons. The course is situated entirely on the grounds surrounding the lake, avoiding public roads and featuring only slight inclines on the shortest distance. Athletes receive guidance from marked distances and event staff throughout the run and bike segments. Spectators benefit from the multi-lap format, allowing them to view competitors multiple times, and a cafe with a balcony provides a view of the transition area. Relay teams of two or three individuals can also participate, dividing the disciplines among members.
