Four-time Olympic gold medallist Ariarne Titmus has announced her shock retirement from swimming, saying the seed was sown by her cancer scare before the Paris Games. The 25-year-old, who grew up in Tasmania, will retire as one of the greatest distance swimmers of all time.
“It’s a tough one but one that I’m really happy with,” she said in a video posted on Instagram. “I’ve always loved swimming … but I’ve taken this time away from the sport and realised some things in my life are more important to me now than swimming.”
Before the Paris Olympics, Titmus underwent surgery to remove two benign tumours after a large growth was found on her right ovary. She described the experience as a turning point that made her consider life beyond swimming.
At the 2024 Paris Games, she won the 400m freestyle in a race dubbed ‘the race of the century’, defeating Katie Ledecky and Summer McIntosh. With that victory, she became the first Australian since Dawn Fraser in 1964 to win back-to-back gold medals in the same event.
Titmus credited Ledecky for pushing her to become a champion. “Without facing Katie, I wouldn’t have been the athlete that I am,” she said. She steps away as the current world record-holder in the 200m freestyle, with 33 international medals, including eight Olympic medals.
Titmus, named Tasmania’s 2025 Young Australian of the Year, plans to work in broadcasting, public speaking, and supporting young swimmers from regional areas.
