London T100


London is calling! Line up on the streets of Britain’s capital and join one of the world’s biggest triathlons. Take on the 100km distance: 2km swim, 80km bike and 18km run or choose from one of the other event distances – all with famous London landmarks as the backdrop to your race.

Following an epic day of racing in 2023 the London Triathlon returns in 2024 under a new name – London T100. The newly branded event will keep all the same distances from last year with the exception of the new 100KM Triathlon replacing the Middle Distance and the introduction of a Pro Race. This fantastic city centre, closed-road triathlon is designed to soak up the summer sun and take in the London sights. Participants will love the support from the crowds along the course, and there’s a variety of distances for all abilities to get involved in.
