London Aquathlon


This event is cancelled due to the London Aquatics Centre being unavailable for event hires during its first months of reopening due to COVID-19 restrictions. We expect to schedule a new date in Spring 2021.


If you're a runner who has considered trying multisport - swim-run, bike-run or triathlon - this beginners' aquathlon is the perfect opportunity to give it a go.

We've created this event with those in mind who might be new to multi-sport events. From great changing facilities to how to manage a perfect poolside transition, you'll be looked after and carefully briefed to take on the challenge with confidence. 

Made of up a super-sprint 400m swim (just 8 lengths of the Olympic pool) followed by a fast 5K run course around the iconic sights of the Queen Elizabeth Olympic Park, you'll find the athletic challenge just enough for a perfect first-time multisport experience. Places are strictly limited to ensure you have a comfortable swim and fellow competitors around you on the run course to keep you going.

Participants are grouped together in waves at 9.00am and 10.00am, with faster swimmers beginning first in each wave, so don't worry about the strength of your swim - we'll ask you for an estimated swim time when you enter. Your actual start time of either 9.00am or 10.00am and arrival time will be given in your final details email sent closer to the event.

As an official British Triathlon permit-holding event, you'll benefit from a professional experience that meets all of the requirements of the sport and introduces you to the technicalities and rules to help you get the most out of your experience.

If you have any questions that aren't answered in the step-by-step guide below, just get in touch on 020 7684 7185 or drop us an email.
