Dorney Lake Duathlon November 2025

Join us for the Dorney Duathlon on Sunday 9th November 2025

Take on a Sprint or Standard distance and take the opportunity to race around this unique and inspiring Olympic venue!!

The flat and scenic grounds lend themselves to a totally flat bike and run course, the ideal venue for a chip timed personal best. Each discipline will be accurately marked out with distance flags and we will have plenty of helpers to keep you on track and to encourage you all the way to the finish.

For those who would like to compete as a team, there is a relay option, which allows 2 or 3 individuals to share the disciplines between them.

Super Sprint = 2.5k run. 10k bike, 2.5k run

Standard = 10k run, 38k bike, 5k run
