This is a preview of the race – click here to read about a super-impressive win for Georgia Taylor-Brown.

The second instalment of this season’s women’s T100 Triathlon World Tour was supposed to see reigning champion Kate Waugh return as part of a stacked middle-distance field.

Missing from the opening fixture of the campaign back in March due to a calf issue, she finally made her 2026 bow at the World Cup in Chengdu earlier this month when she took third after a three-way sprint and then went on to finish 14th at WTCS Yokohama.

But on Wednesday, she posted on Instagram: “Injury update – Super frustrated to have to withdraw from the T100 this weekend due to re-aggravating my calf 🥺. Turns out sprint finishes aren’t the best way to return to racing for calf injuries 🫠. This, combined with the Yokohama race, was just too much load too soon.

“Taking some time to build back again properly and hope to be back again very soon!! Good luck to all the girls in Spain.”

It’s a big shame for her and the race, but there’s still plenty to look forward to with Julie Derron (SUI), Georgia Taylor-Brown (GBR), Holly Lawrence (GBR), and America’s Taylor Spivey all lining up for what promises to be a real cracker.

Here’s all you need to know…

The course in Spain

The course runs through the stunning countryside of historic Pamplona in northeast Spain, with the swim consisting of a 2km stretch through the calm waters of Alloz reservoir, where athletes can expect pleasant temperatures of between 16C and 19C.

Once through T1, the 80km bike course is notorious for its rolling terrain and features a series of undulating sections that will require controlled power and efficient gear management.

The official T100 website suggests that climbs are more ‘steady rather than steep’ but does warn of ‘several sweeping descents and fast corners, where bike-handling skills and confidence play an important role’.

With T2 situated within the city of Pamplona, the 18km run leg starts and finishes within the heart of this most beautiful of historic destinations – taking the athletes around the Arga River on a scenic tour of the Arantzadi neighbourhood before finishing in Gazteluko Plaza.

Pro women’s field

American Taylor Knibb, the winner of this season’s opening T100 race down under on Australia’s Gold Coast, may not be in Spain this weekend, but there are still enough quality athletes on show to whet the appetite for what promises to be a thrilling race.

Seven of the T100 top ten are in the field, while 12 are making their debuts in this year’s new-look championships, which once again means that there is no men’s race on Saturday as the women take centre stage.

The return of Derron, Taylor-Brown, Spivey and Lawrence really does make this a top-class encounter, while the introduction of wildcards Cathia Schär (SUI) and Sophie Evans (GBR) adds a little more spice to the competition.

With Jess Fullager, who was runner-up in Surfers Paradise two months ago, also missing from the starting line-up, the top-ranked athlete is Switzerland’s Imogen Simmonds, who crossed the finish line in third place with an impressive opening race of her campaign.

Home favourite Sara Pérez Sala will be looking to put on a show for her Spanish supporters; Nicole Van Der Kaay (NZL) will be hoping to follow up on her fourth spot that day, while Britain’s India Lee will be seeking to put her injury troubles behind her as she makes her 2026 debut.
