The Eton SuperSprint 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 Sunday 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 a 2 lap loop along the side of the rowing tank on tarmac paths.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!
