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

This event is draft illegal.

Clear water and flat, scenic grounds lend themselves to a fast swim, bike and run course, the ideal venue for a chip timed personal best or for those who dont like racing on open roads.
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 an Aquabike (swim-bike) option, and for those who would like to compete as a team, there is a relay option, with 2 or 3 individuals sharing the disciplines between them.

The flat course is ideal for a personal best over the marathon distance. A whopping 94% of 2021 participants surveyed got a PB at our Dorney Lake Marathon.
Certified by UKA The Marathon @ Dorney Lake has a maximum time restriction of 4 hours, after which there may not be marshals and time keepers available
