Races for all ages and abilities

The Phoenix Aquathlon Series is made up of multiple races for Tristar age groups (age 8-14), a race for youth/juniors and one for adults (age 15+) on a flat and fast circuit at The Guildford Lido. The swim takes place in the open air, 50m lido pool and the run is around the traffic-free perimeter of Stoke Park. The races 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 really hope you’ll come along for an evening of fun and friendly racing.

Lido Map

Guildford lido is one of the few remaining 1930s outdoor pools set in four acres of beautifully landscaped gardens and (in the summer months) heated to 24oC. The olympic-sized pool is a great place to chill out, meet friends picnic and of course swim.

Adult Swim

The adult swim starts after the kids races and is a staggered start so that everyone gets a time. The transition area is at the opposite end of the lido from the kids transition area. See map.

Child Swim

The kids swim starts at one end of the pool where there is a timer and an assistant. At the other end of the pool where they exit, is another person timer and another assistant. Kids exit straight to a dedicated transition area where no adults are permitted ready to don their trainers and start the run.

Adult Run Route

the adult run starts from the main lido car park before turning left past student halls, Guilford bowling club and out into Stoke park. The route runs alongside the Parkway up to the roundabout turning right along London road and then circling back into the park. There is a map below and a GTX file. The route is on tarmac footpaths and there are Marshalls all along the route.

Childrens Run Route

the kids run exits the lido area where the registration tent is before turning right along the Parkway. There are Marshalls at each turnaround point. The route is on a tarmac foot path.
