The second event of the 2025 IRONMAN Pro Series – and the first this year over the full Ironman distance – is set to provide epic action in South Africa this weekend.
Scheduled for Sunday March 30, stellar Pro fields will take on the IRONMAN South Africa course around Nelson Mandela Bay with some of the world’s best triathletes set to feature.
T100 World Champion Marten Van Riel headlines the men’s start list alongside IRONMAN World Championship runner-up Magnus Ditlev – the pair are currently ranked number one and two in the world respectively by the Professional Triathletes Organisation (PTO).
The women’s event includes a handful of worthy contenders including Dutch star Els Visser (PTO 18), Spain’s Marta Sanchez (PTO 19), Germany’s Anne Reischmann (PTO 24), Sweden’s Anna Bergsten (PTO 33) and Denmark’s Maja Stage Nielsen (PTO 36).
Pro Men start list
It will be compulsory viewing as the top two in the world go head-to-head. Van Riel has been a demon over the middle-distance with seven wins in eight races dating back to 2019.
However, on his single previous full-distance appearance in Cozumel last November, he led deep into the bike leg before crashing, costing himself over 20 minutes. He ended the race in seventh place.

He goes up against the Danish juggernaut Ditlev, who has spent the past four years ranked in the world’s top five. He is vastly more experienced over the full distance – boasting four victories in his career. The Dane also finished third at the 2023 IRONMAN World Championship in Nice before going one better in Kona in 2024.
France’s Leon Chevalier is the next best ranked athlete at 27. He bested van Riel in Cozumel as he secured third place and has three successive top-10 finishes at the IRONMAN World Championship. He also has experience on the South African course, winning the event in 2023.
Last year’s race winner can not be overlooked, with Sweden’s Rasmus Svenningsson set to don the number one bib after his success 11 months ago. He also finished in third at the event in 2021 and fourth in 2023 – so Nelson Mandela Bay is a happy hunting ground for him.
In fact there are a plethora of triathletes who have earned podium finishes at the race ready to contend again. 2024 runner-up Mathias Petersen boasts back-to-back podiums in South Africa, Australia’s Cam Wurf has three top-five finishes in four starts and Bradley Weiss has a pair of runner-up medals in his home country.
Elsewhere, New Zealand’s Mike Phillips won IRONMAN New Zealand in early March and USA’s Matt Hanson is a six-time IRONMAN race winner.

Pro Women start list
The women’s race appears to be wide open with six triathletes ranked in the PTO’s top 50 all set to compete.

2021 winner Ruth Astle will also be on the start line, with the British star looking for better days ahead after a tough couple of years. She was able to finish only one race in 2024 and three in 2023 with injuries taking their toll. However she does boast a trio of IRONMAN race victories.
Visser meanwhile ranks fourth in the field on the swim, first on the bike and fourth on the run. She raced 16 times in 2024 and owns three full-distance victories in her career.
