World Triathlon and the Professional Triathletes Organisation (PTO) made a big announcement on Saturday, detailing plans to launch a new series of events in 2027 with what they will call the Triathlon World Tour. The Triathlon World Tour will combine existing T100, World Triathlon Championship Series (WTCS) and World Triathlon Cup events, along with new races that will be announced in the coming months.

The T100 Triathlon World Tour and the WTCS have been a successful pairing so far, with the two series linking up for two race weekends this past season. The first came in the French Riviera in August and the second at the WTCS Finals in Wollongong, Australia, in October.

In 2026, the only WTCS and T100 events that will overlap are races in London, which are slated for July 25 and 26. However, unlike this year’s racing in France and Australia, the T100 event in London next summer won’t feature a pro race, so the only elites racing that weekend will be on the short-course side.

Moving into 2027, it will all change, as the WTCS and World Triathlon Cup systems will get a T100-style makeover. The WTCS will be rebranded as the T50 World Championship Series and the existing world cup events will join what the PTO and World Triathlon are calling the Challenger Series.

Challenger events will be used as a feeder system for athletes to work up to T50- and T100-level racing. World Triathlon Cup races are all short-course events, but when they become part of the the Challenger Series in 2027, they will be open to three distances of racing: T100 (100 kilometres in total), standard and sprint.

All in, the new Triathlon World Tour is expected to feature around 100 races around the globe every year, with multiple new events set to be named in early 2026.

“Our successful collaboration with the T100 Tour has already shown what is possible in terms of event delivery, broadcast audiences and commercial interest, as well as through the events we have trialled together in the French Riviera and in Wollongong in 2025,” said World Triathlon president Antonio Arimany in a press release announcing the news. “This next step is therefore a natural evolution, and we are genuinely excited about what it will mean for the future of triathlon and para-triathlon when we unveil the full Triathlon World Tour early next year.”

The T100 Triathlon World Tour wrapped up its second season on Friday in Qatar, with New Zealand’s Hayden Wilde and Great Britain’s Kate Waugh both taking the individual race wins and series titles on the year. The 2026 T100 season is set to kick off in Gold Coast, Australia, on March 21, while the final year of WTCS-branded racing starts a week later in Abu Dhabi on March 27.
