Event information

Our triathlon is held at Eton Dorney lake in Berkshire, an iconic venue from the 2012 Olympics, ideal for both first timers, and more experienced athletes. Start with a swim in the clear clean waters of the lake, before cycling the car free flat road circuit and then a final run along tarmac woodland paths.

You can choose to do a FULL triathlon, at Olympic or Sprint distance. Or you can form teams, and participate in one or more stage, in RELAY form.
