About the event

The Eton Sprints Weekend triathlons are widely regarded as the official start of the UK triathlon season. Taking place at the fantastic Eton Dorney Lake, one of the iconic venues of the 2012 Olympic Games, the SuperSprint Saturday event starts with a 400m open water swim in the clear, clean waters of the rowing lake before taking to the closed, flat road circuit for a 4-lap bike course covering 21.2k. The final 5k run follows an out and back course along the side of the rowing lake on tarmac paths.

As part of Sunday’s edition, we will be hosting a British Triatlon ITU Qualification event giving participants the opportunity to qualify for the GB Age Group team at the 2021 Sprint Distance World Triathlon Championships. The Sprint Age Group team consists of athletes aged from 16 all the way to 80+. They will compete in five-year age bands, separated by gender. The qualifying event sees a mix of abilities, from top athletes striving to stand on the podium, and others going for the thrill of competing on an international stage.

The venue provides the ideal environment for first time triathletes or experienced athletes looking to get an early season time under their belt and there’s always a buzzing atmosphere for both participants and supporters alike.

Each day will offer two MATES WAVES, in which friends will be able to race together; there is limited capacity for these popular waves, so get in quick if you can.
