Join us for the Dorney Triathlon Lake Triathlon on Wednesday 27th May 2026
Take on a Super Sprint or Sprint triathlon around Dorney Lake on Wednesday 27th May 2026 and take the opportunity to race around this unique and inspiring Olympic venue!
The purpose built lake is perfect for the swim and the flat 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 don’t want to take part in the run, there is also an Aquabike (swim-bike) option.
