Race Day Schedule

Take on a unique swim–run at the iconic London Aquatics Centre in Queen Elizabeth Olympic Park. This event suits first-timers, PB chasers, and anyone who prefers the comfort and precision of an indoor pool before a scenic park run. Entries are open to participants aged 15 and over.

Your race begins with a 400 m pool swim in the world-class London Aquatics Centre. You will then head out for a measured 5 km run around South Park with views of the London Stadium and the Olympic legacy all around you. Expect smooth organisation, supportive marshals, and a lively finish to celebrate your effort.

With RunThrough, you can expect a lively event village and clear guidance from our on-course team. After your run, enjoy food, drink and free finish-line goodies from our partners.

You can add an official event t-shirt to your entry at checkout for more than 30% off. Produced in partnership with RT Kit, it features the event logo on the chest and is the perfect keepsake to celebrate your race. Offering the t-shirt as an optional extra helps us keep entry costs lower for runners who prefer not to include merchandise.
