Ariarne Titmus: Relentless

Olympic champion Ariarne Titmus opens up like never before. 

From humble beginnings in Tasmania to the pinnacle of world swimming, Ariarne Titmus has become one of Australia’s greatest sporting underdog stories. But behind the Olympic gold, fierce rivalries and headlines lies a far more personal story - one of sacrifice, resilience, ambition and the courage to choose a different path.

In her powerful memoir, Relentless, Titmus takes us behind the scenes of the moments that shaped her: the family sacrifices, relentless training and uncompromising determination that earned her the nickname ‘the Terminator’.

Now, for the first time, Titmus shares the full story of her extraordinary rise, and what happened when she made the difficult decision to step away from the spotlight at the height of her career.

Hear Ariarne Titmus in conversation with HerCanberra’s Emma Macdonald about the triumphs, sacrifices and choices behind the medals - and the person she became beyond the pool.

Ariarne Titmus

World record holder and four-time Olympic gold medallist Ariarne Titmus is one of the greatest middle-distance swimmers of all time.

At the 2024 Paris Olympics, Ariarne achieved a historic 3rd individual Olympic gold medal, winning the 400m freestyle, in what was dubbed 'the race of the century', where she defeated the other two previous world record holders of this event – American all-time great Katie Ledecky and Canadian swimming prodigy Summer McIntosh – to become the first Australian athlete since Dawn Fraser in 1964 to win back-to-back gold medals in the same event.

Known as 'the Terminator', Ariarne is renowned for her grit and determination. Throughout her career she overcame significant challenges, including recovering from a shoulder injury only months out from the Tokyo 2020 Olympic Games, and from surgery to remove a tumour on her ovary in 2023, a journey she shared publicly as one of the scariest times of her life.

Overcoming challenges and pressure to be the best when it counts on the big stage, time and time again, is what has placed Ariarne in a league of her own, making her an inspiration to many.

In October 2025, Ariarne announced her retirement from swimming to pursue other interests. She is an admired public speaker, a keen foodie and a sports fan, especially of AFL and tennis.
