Stars and Stripes vs The World: First Athletes Confirmed For Supertri Pro Series in Austin
Supertri’s international stars will take on the USA’s top emerging talent when the Supertri Pro Series kicks-off in Austin on May 25, with amateurs getting the chance to join the elites by racing on the same course on the same day.
The opening wave of athlete announcements reveals a compelling international versus American storyline at Ascension Seton Supertri Austin, with decorated talent squaring off against the country's most promising professionals on one of the fastest courses on the triathlon calendar.
The first edition of the Supertri Pro Series, which sees athletes competing over a draft-legal sprint distance format before thousands of amateurs swim, bike and run the same course, will see the likes of Fanni Szalai, Seth Rider, Mathis Beaulieu and Olympic gold medallist Tim Hellwig providing stiff competition for the cream of US development athletes, who will be announced in race week.
Hungary’s Szalai, 18, has come through the ranks at Supertri after bursting onto the scene as a 15-year-old at Supertri E in Switzerland when she stunned the triathlon world with a podium finish. She is now one of the most decorated junior athletes of all time.
Rider is a more established US star, and was part of the USA’s Olympic silver medal winning mixed relay team at the Paris Olympics. Canada’s Beaulieu is one of the rising stars of the sport, while Hellwig collected the mixed team gold with Germany in Paris, and is making his way back to the top after injury. Other international stars also confirmed include Zuzana Michaličková, who finished 8th overall in Supertri in 2025, and Diana Isakova.
The Pro Series event is being run in conjunction with USA Triathlon to provide elite development opportunities for athletes ahead of the LA 2028 Olympics. It further strengthens the partnership between Supertri and USA Triathlon after the recent announcement that Supertri Long Beach and Supertri New Jersey will host two rounds of the USA Paratriathlon Nationals Qualifier Series on the same day.
Supertri Pro Series events pay 10 deep to encourage athlete development. As well as these international stars, three athletes per gender will also qualify for the Supertri Pro Series Final with its $800,000 prize pool.

Ascension Seton Supertri Austin, USA — May 25

The date and location for the Supertri Pro Series Final will be announced in May. The full Austin start list will be confirmed in race week.
