Event overview

Clear water and flat, scenic grounds make for a fast swim, bike and run course.

It's the ideal venue for a chip-timed personal best or for those who don't like racing on open roads. There will be plenty of helpers to keep you on track and encourage you all the way to the finish.

For those who don’t want to take part in the run, there is an Aquabike (swim-bike) option, and for those who would like to compete as a team, there is a relay option, with 2 or 3 individuals sharing the disciplines between them.
