What is T100 Triathlon? All you need to know about the new race series attracting the sport’s stars
We answer all your questions about T100, a middle-distance series attracting many of the world's top triathletes.
The T100 Triathlon is a globetrotting series of professional and amateur triathlon races, set apart by its 100km distance, dynamic medium-course racing and star-studded field.
Organised by the Professional Triathletes Organisation (PTO), the T100 Triathlon World Tour pits the world’s top triathletes against each other in a season-long championship, while offering amateur athletes the chance to race on the same courses.
Why is it called T100 Triathlon?
T100 gets its name from the total race distance of 100 kilometres (60 miles), which breaks down into:
- 2km / 1.2mi swim
- 80km / 49.7mi bike
- 18km / 11.2mi run
The T100 is a medium length triathlon race distance. It’s shorter than both a half and full Ironman, which amount to 70.3mi / 113km and 140.6mi / 226.3km respectively, in a bid to make the format more explosive and exciting while also testing the athlete’s stamina.
Another benefit of the 100km distance is that it draws in both short-course and long-course athletes. They rarely race each other on a level footing, making for a compelling contest.
What is the T100 Triathlon World Tour?
The centerpiece of the T100 is its professional race series, the T100 Triathlon World Tour. Contracted athletes and invitees compete at the calendar events to win the individual events while accumulating league points and prize money.
In the 2026 season, the professional women will race in Australia, Spain, Canada and Dubai. The men will compete in Singapore, San Francisco, France and Saudi Arabia. Both will take part in the Grand Final in Qatar.
- 21-22 March Gold Coast, Australia — women’s pro race
- 25-26 April: Singapore — men’s pro race
- 23-24 May: Spain — women’s pro race
- 6-7 June: San Francisco — men’s pro race

World Triathlon also recognises the T100 Triathlon World Tour as the official World Championship tour for long-distance triathlon.
Who’s racing the T100 Triathlon World Tour in 2026?
The T100 World Tour start list includes forty of the world’s best female and male triathletes (20 of each gender), who will contest a series of nine races, finishing with the T100 Grand Final in Qatar.
The top ten finishers in last year’s rankings earned an invitation to race this year. T100 picks another eight men and women from the top 30 in the PTO World Rankings, based on 2025 performances.
An additional two spots per race are reserved for Wildcards, who haven’t met the entry criteria but deserve inclusion. They still can earn prize money, points and the right to be automatically selected next year.
The start list for the women’s season opener on the Gold Coast has been annnounced. Big names competing include defending champion Kate Waugh, Julie Derron, Ellie Salthouse and Taylor Knibb.
On the men’s side, names are yet to be confirmed for the Singapore start.
How did the 2025 T100 World Tour go?
Kate Waugh was crowned the women’s T100 World Tour champion and Hayden wilde won the men’s event.
Both dominated throughout with the Brit leading for most of the series and New Zealander winning six times out of seven starts.
Women’s runner up Georgia Taylor-Brown was followed by Julie Derron, who also finished third in 2024.
Defending champion Marten Van Riel dropped down to third behind Mika Noodt.
How much do T100 triathletes get paid?
The T100 World Tour prize money pot is pretty big. T100 awarded a total of $7million in 2025 comprising $3million in contracts, $2million in prize money and $2million in final tour rankings. Men and women receive equal pay.
Not counting their contract payments, 2025 champions Kate Waugh and Hayden Wilde won $338,000 and $350,000 respectively.
Can anyone do a T100 triathlon?
The T100 World Tour is reserved for the top ten female and male triathletes from the previous year’s rankings, the top six women and men in the PTO world rankings and four wildcards.
But at an amateur level, anyone can race.
Most T100 events organise amateur races on the same course and closed roads as the professionals with distances ranging from 100km to Olympic and Sprint. Dubai also puts on a corporate duathlon relay.
The entry fees for the French Riviera T100, for example, are €360 for the 100km, €125 for the Olympic distance and €95 for the Sprint distance.
What is the average time for the T100 Triathlon?
Male pro triathletes finish the 2km swim, 80km bike and 18km run in about 3 hours and 20 minutes. Elite women take around 3 hours and 45 minutes.
However the fastest finishers can go much quicker. Taylor Knibb clocked 3:29:17hrs in the 2024 Dubai Grand Final and Marten Van Riel crossed the line in 3:09:17hrs.
A good amateur triathlon time in the T100 is harder to pinpoint.
At the London T100, the quickest female amateur took 4:03:04hrs and the speediest male amateur finished in 3:33:12hrs.
For women, a time faster than 4.5 hours would have got you into the top 15. Going sub-five hours would secure you a top 60 finish while the mid pack finished in 5.5 hours.
Sub-five hours represents a solid age-grouper effort for men (top 400 out of 1000 in London). More ambitious amateurs may target 4.5 hours for a sub-200 finish. The top 30 amateur men went under the four-hour mark.
On a harder course though, finishing under six hours would still be an achievement.
