A Global Weekend of Racing with Plenty to Watch

This weekend in triathlon stretches across the globe, with storylines building from Spain to Lanzarote to Slovakia and into Texas. Different formats, different stakes, but no shortage of reasons to tune in.

Spain T100: All Eyes on the Women

The spotlight lands first on the women’s field at the second women’s T100 race of the season, set against the Alloz Reservoir in Navarra-Pamplona. Twenty professional athletes are set to line up with a $275,000 USD prize purse on offer.

Imogen Simmonds leads the start list as the current number three in the T100 standings, joined by Nicole Van Der Kaay, Bianca Bogen, and Sara Pérez Sala, ranked fourth, fifth, and sixth respectively. (However, a reminder that only those who raced the Gold Coast season-opener currently have points on the leaderboard.)

For several big names, this represents their first T100 appearance this season, including Julie Derron, Georgia Taylor-Brown, Holly Lawrence, Taylor Spivey, and India Lee.

Derron opened her 2026 season exactly where she left off. After finishing second overall in the 2025 T100 series, she started the year with a win at Challenge Taiwan Half. In nine T100 starts, she has only missed the podium twice. She is also arriving as the current number one in the PTO World Rankings.

Taylor-Brown, after a fourth place finish at the WTCS race in Samarkand, spoke about where her head is at this season: “[I’m] wanting to race and wanting to win and feeling like the biggest thing for me is feeling like I can win.” She also appeared to gain notable momentum at the end of last season with more experience at the middle distance, finishing fourth at the Ironman 70.3 World Championships in Marbella and second at the T100 World Championship Final in Qatar. It will be exciting to see her take on this distance again.

Watch live: May 23 at 12:05 Pamplona (UTC+2) on Triathlonlive.tv or T100 YouTube.

Ironman Lanzarote: Qualification and Validation

Ironman Lanzarote is not about prize money or Pro Series points; it is about Kona. Slots are scarce, and past and present champions are here for what remains. This race offers three qualifying slots per gender, and there are a total of 23 still remaining ahead of the mid-August qualification deadline.

For Sam Laidlow and Lucy Charles-Barclay, it is simply about validation. For Patrick Lange, it is about securing a slot outright.

Charles-Barclay faces a true test at the full distance following early-season Achilles surgery, while Laidlow lines up for his first full distance race of the year after winning Ironman 70.3 Valencia.

Follow every minute of the race through the Ironman Tracker App. Race start is 7:00 am (GMT+1) on May 23.

The Championship in Samorin

The Championship Samorin returns as Challenge Family’s flagship middle distance event, bringing together the best age group and professional athletes to race for the title. A share of the €100,000 prize purse is on the line for the pros.

A sold-out field of more than 2,400 athletes, including 80 of triathlon’s elite racers, will line up at the x-bionic sphere near Bratislava for the largest edition of the race to date.

Katrine Græsbøll Christensen is arriving for her first Challenge Championship following a win at Challenge Sir Bani Yas and a second place finish at Ironman South Africa. Daniel Baekkegard is also making his debut at this event, racing for the first time since Challenge Roth in 2025. Also lining up for their first Championship appearances are Justine Guérard, Jannik Schaufler, and Lena Meissner.

Marta Sanchez will continue her run for podiums this season, following third place finishes at Ironman Texas and Challenge Salou. Caroline Pohle is returning for her second Championship appearance after finishing second in 2023 and winning Challenge Mogán-Gran Canaria earlier this year. Henry Rappo, who finished second last year, and Kieran Lindars, third, are also back on the start line.

Veterans of the course Pieter Heemeryck and Frederic Funk are returning for the seventh time.

Watch Live: May 24 starting at 8:15 am CEST on www.challenge-family.live.

Supertri Austin

To close the weekend, the first Supertri Pro Series stop of the season lands in Austin, Texas. This draft-legal sprint format offers a $35,000 USD prize purse and six qualifying spots for the series final.

Notable names on the start list include Gwen Jorgensen, Tim Hellwig, and Seth Rider.

The professional race starts at 6:45 am (GMT-5) on May 25.
