Enjoy the fun and friendly race atmosphere at the beautiful guildford Lido and scenic Stoke Park.

Each event in the Phoenix Aquathlon Series is made up of four races for Tristar age groups (age 8-14) and a race for youth/juniors and adults (age 15+) on a flat and fast circuit, starting and finishing at The Guildford Lido. The swim takes place in the open air, 50m lido pool and the run route takes you around the traffic free perimeter of the neighbouring Stoke Park.

The races on all four dates are identical so it's a great way to compare your times for each race and see how your fitness improves throughout the season! We welcome entrants of all abilities and we really hope you'll come along for an evening of fun and friendly racing.

Hello, I did my first race last year and it was fantastic. One thing I will always remember is how kind, friendly and supportive the marshals and the team members were.
