London T100, live.

Racing past Tower Bridge and the London Eye

The London T100 is a weekend of triathlon in central London on 21 and 22 August 2027, one of the T100 Triathlon events around the world.

The headline race is the 100 km triathlon: a 2 km swim, 80 km on the bike and an 18 km run, the distance the professionals race on the tour. The route passes landmarks such as Tower Bridge and the London Eye, with crowds lining the course.

Three shorter races complete the programme. The Olympic distance is 1.5 km, 40 km and 10 km, the distance raced at the Olympic Games. The sprint is 750 m, 20 km and 5 km, and the super sprint is 400 m, 10 km and 2.5 km, a short and sharp first taste of the sport.

Every T100 Triathlon event is a qualifier for the T100 age group world championship finals in Qatar, and the tour is recognised by World Triathlon as the official world championship tour of long distance triathlon.

With four distances over two days the event suits first time triathletes and seasoned competitors alike, and supporters have races to watch on both days.
