Season Finale | Sunday 18th September 2022

What is Season Finale?

The Season Finale Triathlon brings curtain down on the triathlon season with a final chance to race in cooler late-summer temperatures. It’s hosted at the iconic Dorney Lake rowing centre, a first-class triathlon venue offering clear/calm waters and a flat, fast run/cycle course. Also known for its electric atmosphere, the closed-road circuit means that you are continuously supported even in the toughest moments.

This is the perfect event for triathletes of all abilities, there is the First-Timers wave which offers shorter distances allowing those new-comers to triathlon to get a feel for the event, all the way up to the Olympic distance which offers a replica event to those competing for their country. There’s a range of distances available, including the return of the popular duathlon, and the younger members of the family can join the fun too with children’s race options.

Hundreds of people return annually to experience the event again, so make sure you secure a place for 2022 at the lower price currently available.
