Your place in the race

Set at the venue that hosted the rowing events during the London 2012 Olympic Games, the Dorney Lake Triathlon offers a fantastic opportunity to challenge yourself in a truly inspiring setting. The purpose-built lake provides calm open water for the swim, while the flat bike and run routes make this event ideal for both experienced triathletes and those taking on their first standard-distance triathlon.

The Standard Distance event includes a 1,500m swim, approximately 38–40km bike ride and a 10km run around the scenic, traffic-free grounds of Dorney Lake. The fast, flat course makes it perfect for chasing a personal best while enjoying a supportive and welcoming atmosphere.
