Now in its 22nd year, the London Triathlon has recently been voted for by YOU, our participants, as the UK’s Best Multi-Sport Event and we’re ready to make 2021 better than ever before! Every year, thousands of people come to our iconic capital city to join our community of incredible triathletes taking on the challenge of #TheLondonTri.

Or alternatively, grab your mates and join in the fun by entering a Sprint or Olympic Team Relay. Are you ready to push yourself and take on a challenge?
