The Professional Triathletes Organisation (PTO) will be working with London Marathon Events (LME) to deliver the London T100 triathlon, taking place in the city on 27 and 28 July 2024. The event is the London leg of the new T100 Triathlon World Tour.

LME is one of the world’s leading event organisers with a portfolio of events that includes the TCS London Marathon, the Ford RideLondon festival of cycling, Swim Serpentine and a range of running events for all ages and abilities. LME was also responsible for the operational delivery of the INEOS 1:59 Challenge when Eliud Kipchoge became the first man in history to run a sub-two-hour marathon.

Commenting on the news, PTO CEO Sam Renouf said: “We want London to become one of the signature legs on the new T100 Triathlon World Tour, so it was very important for us to work with a world-class team like London Marathon Events. London has a prestigious history in the sport, having hosted the world’s largest Triathlon for many years and the 2012 Olympic races seeing hundreds of thousands coming to spectate. This partnership with LME will see London return to hosting a truly ‘bucket list’ status event in Triathlon – for amateurs and professionals.”

Hugh Brasher, Event Director for LME, said: “Every year, the team at London Marathon Events delivers the world’s greatest marathon, a UCI Women’s WorldTour cycling race and the UK’s biggest open water swimming event. We are delighted to be working with the PTO to deliver the professional and amateur triathlons in July, showcasing London to the world through global TV coverage, and we look forward to inspiring more runners, cyclists and swimmers to take on a triathlon.”

Excitingly, for both amateur triathletes and everyday athletes looking for their next challenge, the London T100 offers everyone the chance to take part. The event caters for participants of all abilities, with distances ranging from:

  • Super Sprint Triathlon (0.4km Swim, 10km Bike, 2.5km Run)
  • Sprint Triathlon (0.75km Swim, 20km Bike, 5km Run)
  • Olympic Triathlon (1.5km Swim, 40km Bike, 10km Run)
  • T100 Triathlon (2km Swim, 80km Bike, 18km Run)

The event course uses closed roads throughout and takes in the magnificent and iconic sights of central London. What’s more, amateur athletes will be racing on the same course as the pros, meaning that everyone will get to experience the incredible atmosphere and a totally unique event experience. The T100 distance is sold out due to high demand, but there are a final few places left for the Olympic, Sprint and Super Sprint distances taking place on Sunday 28 July.

The London T100 will be the fourth stop on the new eight-leg T100 Triathlon World Tour, which sees the world’s best triathletes compete consistently, head-to-head in iconic cities around the world over the new 100km distance (2km swim, 80km bike, 18km run) on a global broadcast feed across 195+ territories. The next stop is the San Francisco T100 on 8 and 9 June 2024.
