About this event

📅 26th September 2026

👣 Triathlon

The Dorney Lake Triathlon Standard is a fantastic endurance challenge for those ready to take on a longer triathlon. Bringing together swimming, cycling and running, this event will test your fitness, stamina and determination from the first discipline to the final run.

It’s a challenge that involves a 1500m swim, 38km bike and a 10km run, and requires preparation and commitment.

But crossing the finish line after completing all three disciplines makes every training session worthwhile! Whether you’re an experienced triathlete or looking for your next major sporting goal, this is an event to put firmly on your challenge list.
