We are often asked if wetsuits have to be worn at our events. But the wearing of wetsuits in triathlon is governed by British Triathlon rules and is totally dependent on water temperature one hour before the start of the event. Read the wetsuit rule for triathlons HERE.

Full on-site parking means you can come and go while the event is taking place, we have showers and toilets aplenty and there is catering in the Boathouse.


1st time triathlon

I completed the Sprint Triathlon

There is a reason that Dorney Lake hosted events for the 2012 olymics. Great settings and spectator view points.

Great experience for my 1st triathlon. The cycle course is closed, so you don't have to fret about traffic / cars. Flat terrain so you just need to concentrate on the distance.
