About the race
Phoenix Tri Aquathlon Series is a multi-race aquathlon held by Phoenix Triathlon Club at Guildford Lido with running around Stoke Park. The series includes separate races for children, youth/juniors, and adults on a flat circuit at the lido and in the park.
The swim takes place in the open-air 50 m lido pool and the run follows traffic-free, fully marshalled tarmac footpaths around the perimeter of Stoke Park. The venue, Guildford Lido, is an outdoor pool set in landscaped gardens and is heated in summer months.
Race dates for 2026 are listed for June, July and September, and a discount is offered to entrants who enter all three races. Race format notes: children's races start at one end of the pool with a timer and an assistant, and children exit directly into a dedicated transition area where adults are not permitted. The adult swim follows with a staggered start so individual times are recorded. Multiple past results are recorded for previous years.
