Four-time Olympic gold medallist Ariarne Titmus has announced her retirement from swimming at the age of 25, citing a cancer scare before the Paris Games as a turning point. The Australian star, who grew up in Tasmania, revealed the decision in an Instagram video, saying she realised that personal goals had become more important than swimming.
Titmus underwent surgery to remove two benign tumours after a large growth was found on her right ovary before the Paris Olympics. She described the health challenges as a moment that 'really rocked me mentally' and led her to consider life beyond the pool. 'I've always loved swimming, but I've taken this time away and realised some things in my life are just a little bit more important,' she said.
At the Paris 2024 Games, Titmus won the 400m freestyle in what was dubbed 'the race of the century', defeating American great Katie Ledecky and Canadian prodigy Summer McIntosh. She became the first Australian woman since Dawn Fraser in 1964 to win back-to-back gold medals in the same event. Titmus credited Ledecky for pushing her to greatness, calling her Tokyo 2020 victory over the 'GOAT' her greatest achievement.
Titmus retires as the current 200m freestyle world record-holder, with a total of 33 international medals, including eight Olympic medals (four gold, three silver, one bronze) and four world titles. She also confirmed her relationship with fellow Australian swimmer Kyle Chalmers, though details were not disclosed in the announcement.
Looking ahead, Titmus plans to work in broadcasting and public speaking, as well as giving back to swimming by mentoring young athletes from regional areas. She was named Tasmania's 2025 Young Australian of the Year.
