The World’s biggest triathlon welcomes over 13,000 triathletes to swim, bike and run around London's landmarks.
You’ll be treated to an unforgettable open water swim in the Thames from London Docklands, wiz through London’s under-pass tunnels (watch out for the climb on the way out!) and a blisteringly fast an all importantly flat run around the impressive 2012 Olympic venue, the Excel.
Each year thousands of supporters bring the noise and add to the energy and incredible atmosphere of the triathlon. Impressive high-rise views of London as well as taking a tour of some of its landmarks await you, but more importantly, be prepared to be pushed to your limits like no other endurance event.
Join some of the world’s best athletes and go toe to toe in sprint distance triathlon. Take on the most popular event at the London Triathlon, the sprint. The Sprint is challenging, yet achievable for all levels of triathlete – whether you’re stepping up your game from the super sprint or just want to go all out for the fastest time!
Show London what you’re made of.

Sign up for a new challenge and support a charity of your choice, even before general entries are open! Each charity will have their own fundraising target and incentives to help you get there. By becoming part of a charity team, you'll get some much-needed support in the run up to the event, on the big day itself and beyond.
The route is made up multiple laps. The opening swim takes place in London Docklands; you’ll then transition to bike inside the Olympic venue of the Excel. You’ll then follow a closed road cycle route taking in some of London’s best land marks roughly following the Thames – this section is made up of multiple laps. A final transition inside the Excel before running in and around the building itself.
