London Aquathlon October 2027

Join us for the London Aquathlon on Saturday 23rd October 2027!

Take on a unique swim-run challenge at the iconic London Aquatics Centre and Queen Elizabeth Olympic Park.

The event begins with a 400m pool swim inside the world-class London Aquatics Centre before heading outdoors for a scenic 5K run around South Park. Along the route, you’ll pass the London Stadium and take in the surroundings of one of London’s most recognisable sporting destinations.

With indoor pool facilities and a measured run course, the London Aquathlon is a great choice for first-timers, athletes chasing a personal best, and anyone looking to experience a different type of race challenge.

Entries are open to participants aged 15 and over.

You can now grab your London Aquathlon event t-shirt for more than 30% off when you buy it as part of your entry on checkout! With the event logo printed on the chest, it’s the perfect keepsake to celebrate your race and wear your achievement with pride!

We can do this with our partner RT Kit as part of a strategic decision to raise awareness about the quality of the product, whilst reducing the overall cost of events for those who would prefer not to have a t-shirt included.

Come and enjoy the day with us. Once you enter, you will receive a confirmation email. More information will be sent closer to the event. We can’t wait to see you on the start line.
