London T100 Triathlon

Britain’s capital plays host to the T100’s elite; a race course studded with iconic landmarks promises to provide history-making moments for both athletes and fans. 

The first London T100 Triathlon weekend is entirely free for spectators coming down, and includes a dedicated T100 Watch Party for the very first time. 

The T100 Watch Party will enable fans to see the world’s best triathletes at least 16 times in the flesh during the entertaining 100km race format (2km swim, 80km run, 18km swim), including the start of the swim, the two transitions – from swim to bike and then bike to run – and then the exciting race finish. 

As well as the professional races, the London T100 Triathlon weekend offers the chance for everyone to take part, with 5,000 age-group athletes making this one of the largest Triathlons in the world.
