London Aquathlon

London Aquatics Centre, LONDON. E20 2AQ

If you're a runner who has considered trying multisport, this aquathlon is the perfect opportunity to give it a go, and why not at the Olympic Park and Aquatics Centre, home of the 2012 Games!


We've created this event for those who may 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.


With 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, grouped together in waves (8:00am, 8:40am, 9:20am) and released in 15-second intervals, will be allocated an exact swim start time between 8:00am and 9:40am - communicated in the week leading up to the event, together with a recommended arrival time at least 30 minutes prior to their start wave.


Faster swimmers will begin first within each wave - determined by the estimated 400m swim time provided during registration to minimise congestion – but all participants will be randomly allocated to one of the three waves.


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


Event merchandise is available for purchase during registration for delivery by the following weekend when ordered by Sunday.


All of our events are organised following government and governing body COVID-19 guidance. We will continue to ensure that we deliver safe and enjoyable events.


Entry on the day will be subject to availability and a £5 surcharge.
