Roos Vanotterdijk Sets Belgian 50 Back Mark In Stockholm As Kyle Chalmers Rattles Australian 50 Fly Record
Roos Vanotterdijk set a Belgian 50 back record and Kyle Chalmers rattled the Australian 50 fly mark on a day at the Swim Open Stockholm when Lukas Märtens downed the long-standing 400 free WR.
Iona Anderson of Australia won the women’s 50 back in 27.58 ahead of Vanotterdijk who swam a Belgian record of 27.81, slicing 0.16 from the standard of 27.97 she set at the Flemish Championships in 2023. Marrit Steenbergen was third in 28.22.
Vanotterdijk returned for the 50 fly where just 0.02 separated the first three women home. Sara Junevik got the touch in 25.88 ahead of Angelina Köhler (25.89) and Vanotterdijk (25.90).

Chalmers has enjoyed a fine time in recent weeks. The nine-time Olympic medallist went top of the 100 free rankings in 47.27 – the fourth-fastest of his career – at the Bergen Swim Festival before firing off a 21.78 PB over 50m.
On to the Swedish capital and the 26-year-old fired off a 22.89 PB in the 50 fly. Only Matthew Targett has gone quicker among Australians with a national record of 22.73 that secured silver at the 2009 World Championships and that still stands as an Oceania standard today.
Chalmers’ PB ahead of Stockholm stood at 23.10 from the 2024 Australian Championships from which he sliced 0.21 as he became only the second Australian inside 23secs.
Nyls Korstanje of the Netherlands was second in 23.02 with Konrad Czerniak and Casper Puggaard sharing third in 23.54.
Gose Prevails In Duel With Johnson
Olympic bronze medallist Isabel Gose enjoyed a fine duel with Moesha Johnson of Australia in the women’s 1500 free with the pair trading the lead. Come the final turn and Johnson led by just 0.01 before Gose accelerated with a 29.81 final 50 propelling her past the Paris 10k silver medallist in 15:58.17 to 15:58.53.

It was the eighth fastest of the German’s career topped by her 15:41.16 national record en-route to the Paris podium and the fourth swiftest performance by Johnson. The pair propelled themselves to the top two slots in the 2025 rankings.
Ksawery Masiuk dominated the men’s 200 back in 1:58.46, Jan Kalusowski won the opening title of the meet with a 2:10.49 victory in the men’s 200m breaststroke. Dawid Wiekiera made it a Poland 1-2 in 2:12.26 with Lucas Matzerath of Germany third in 2:12.45.
Iris Julia Berger came from fourth at the final turn to make her way through the field for a 1:59.46 victory in the women’s 200 free. She was followed by German duo Lise Seidel (1:59.61) and Nina Holt (1:59.71) as 0.25 separated the trio.
