About the race
The London Aquathlon takes place on 25 October 2026 at the London Aquatics Centre in Queen Elizabeth Olympic Park, London. The event combines a pool swim with a measured park run and is open to participants aged 15 and over.
The race begins with a 400 m pool swim and continues with a 5 km measured run around South Park, with views of the London Stadium and the Olympic legacy. The swim comprises 4 lengths (8 laps). Each kilometre of the run is marked with distance flags and marshals guide and cheer participants around the course.
Included with entry are a themed medal, free race photos, chip-timed results, and post-race goodies. The organiser provides marshals around the course and operates an event village with food and drink options, plus partner giveaways at the finish. The event notes an available event t-shirt at more than 30% off when purchased as part of an entry, produced in partnership with RT Kit. The organiser also highlights ongoing work on sustainability measures for its events. Visit the organization's website for the most recent information.
