This unique and inspiring Olympic venue plays host to the penultimate round of British Triathlon's Super Series on Sunday, August 24th, 2025.

The clear water and a flat, traffic-free bike and run lends itself to a fast swim, bike and run course, the ideal venue for this Eton Eliminator.

The venue will open at 7am with registration opening at 7:30am.

All YouthB/Junior/Senior races will take place over the distances of Swim-350m, Bike-4.8km, Run-1.5km, starting at 9am.
The Heats and Rounds will use the following formats:
Heats: Swim-Bike-Run 
Round 1: Run-Bike-Swim
Round 2: Run-Swim-Bike (finish after a third transition)
Round 3 (final): Swim-Bike-Run - only top two-thirds of finishers from Round 2 will compete in Round 3. Results for those dont compete in Round 3 will be taken from Round 2.

In the afternoon, YouthA will take centre stage races with races over the distances of Swim-300m, Bike-4.8km, Run-1km 
The Heats and Rounds will use the following formats:
Heats - Swim-Bike-Run
Round 1 - Run-Bike-Swim
Round 2 (final) - Run-Swim-Bike (finish after transition)

As well as the change in discipline order, each round will result in smaller start waves (for example):

Round 1 - 2 waves of 30
Round 2 - 3 waves of 20
Round 3 - 3 waves of 14 (YouthB/Jun/Sen only - 1/3 eliminated)
