How to watch San Francisco T100

After an outstanding season starter in Singapore in April, the T100 Triathlon World Tour continues on 31 May in San Francisco, US.

So here’s everything you need to know about the 2025 nine-event T100, who will be racing in the second round, and, crucially, how to make sure you don’t miss a second of the action…

What is the T100 Triathlon World Tour?

The T100 Triathlon World Tour is a race series that’s recognised by World Triathlon as the official world championship tour of long-distance triathlon.

Forty of the world’s best female and male pros (20 each gender) compete over nine races culminating in the T100 Grand Final in Qatar, in December.

For 2025, the top 10 of each gender from 2024’s T100 Tour rankings automatically received an invite to race (16 have taken up contracts). The remaining slots have been filled from the PTO World Rankings, reflective of outstanding performances in 2024.

Additional ‘Hot Shot’ contracts have been allocated to ‘those athletes who’ve earned the right to race through Olympic success or their standing in the sport outside of their PTO World Ranking Position.’
 
And then there are ‘Wildcard’ (non-contracted) athletes for each event. These are chosen based on exceptional recent performances, top athletes coming back from injury or maternity or more Olympians stepping up in distance. They can still earn prize money, points and the chance at a 2026 contract.

For a full run-down of who’s been given what contract, head here.

Athletes are racing for a hefty prize fund of $250,000 per event, with $25,000 awarded to first place, $16,000 to second place and $12,000 to third. Across the nine races that totals $2million of prize money.

There’ll also be a $200,000 prize for the series winners after the Grand Final, with other athletes also awarded money based on their ranking at the end of the series. This comes from an additional prize pool of $2million.

How does the T100 points system work?

Athletes score 35 points for first place to 1 point for 20th place at each of the nine races, which contribute towards their T100 ‘Race To Qatar’ ranking.

The Qatar T100 Triathlon World Championship Final has increased points – 55pts down to 4pts.

Each athlete’s best four T100 race scores plus the Qatar T100 Triathlon World Championship Final will count towards the women’s and men’s T100 World Championship titles.

What happened in the T100 Series in 2024?

The first round in Miami at the start of March saw wins for India Lee and Magnus Ditlev.

The Tour then moved on to Singapore in April where Ashleigh Gentle was back on top of the podium in the women’s event, while there was a surprise win for Dutchman Youri Keulen in the men’s.

At the start of June, Marten Van Riel and Taylor Knibb triumphed at the third round in San Francisco.

London played host to the fourth round as part of the new-look London Triathlon. In the capital, Gentle was a class act but home favourite Lucy Charles-Barclay made an uncharacteristic DNF. For the men, reigning Ironman world champ Sam Laidlow took victory.

In the fifth race, Knibb and Van Riel made it two wins from two T100 starts in Ibiza. Plus, India Lee produces the best British performance to hold on for the podium and Alistair Brownlee finishes fourth in the men’s race.

The T100 travelling circus headed to Lake Las Vegas for the sixth and penultimate round, where Jelle Geens beat Van Riel in the battle of the Belgians, and Knibb make it three for three on home soil.

At the Grand Final in Dubai, Van Riel and Knibb made history by winning the final race and also the first-ever T100 title… and collected a decent chunk of change for their colossal efforts.

What’s happened in the 2025 T100 Series so far?

The first round in Singapore saw a superb shock win for Hot Shot female pro Kate Waugh. While in the men’s race it was an Olympic showdown for two T100 newbies, as Paris silver medallist Hayden Wilde once again outshone Paris bronze medallist Léo Bergere for the win. Reigning champ Van Riel ran in for third – but he did race an Ironman (and qualify for the Worlds in Nice) just one week earlier.

When and where is San Francisco T100 taking place?

The second race of the 2025 T100 takes place in San Francisco, California, USA, on 31 May.

What distances will athletes race in San Francisco T100?

All T100 races will feature a 2km swim, 80km bike and 18km run, which equals 100km, hence the name of the series.

Who will be racing San Francisco T100?

The most anticipated battle in the second round will be between Singapore winner Kate Waugh and the reigning champion and 2024 San Francisco winner, Taylor Knibb.

Ashleigh Gentle will also be on the startline, hoping to improve from a disappointing sixth-place finish in Singapore. Also looking for improvement will be Paris silver medallist Julie Derron, 12th in Singapore; Olympic champion Flora Duffy, who DNF’d in the first race; and Canada’s Paula Findlay, who is starting her 2025 T100 campaign after a solid win Ironman 70.3 Oceanside in April.

Joining Waugh for GB is Olympic swim legend Jess Learmonth, who won huge kudos for the way she raced in Singapore, pushing the pace hard on the swim and bike to lead going into the run, before overheating but refusing to pull out, eventually finishing 13th.

Olympian Taylor Spivey will also be racing on home soil after an encouraging fifth-place finish in Singapore.

On the men’s side, reigning champion Van Riel, Kyle Smith and Rico Bogen will line up for a possible repeat of last year’s San Fran sprint finish where the Belgian just edged out Smith by less than a second for the win; with Bogen only a further 3secs back.

Home favourites Sam Long, Jason West and Morgan Pearson will also be on the startline, the latter racing two weeks after WTCS Yokohama as the US run star continues his Olympic/T100 juggle in 2025. Pearson had been set to start his T100 campaign in Singapore but was forced to DNS due to a fractured wrist.
