London Triathlon - Olympic

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 Olympic distance triathlon. Hugely popular and must-do distance for any triathlete. It’ll be a challenge, but you know that, yet you can achieve greatness in London with a booming crowd behind you.

Show London what you’re made of.

Route

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.

Tips for the big day

• Road closures make it difficult to get into London on event day, so we recommend racking your bike up the day before and taking public transport in.
• The transition hall is massive, so ensure you remember where you racked your bike to ensure minimal transition time
• Go easy on the turn backs on the bike section; it can get slippery.
• Enjoy the day and take in an amazing atmosphere!
