A meteoric rise throughout the last four years has readied 20-year-old Ariarne Titmus for her Olympic debut in Tokyo.
The Tasmanian native first stamped her mark on the world swimming stage at the 2017 World Championships, where she earned bronze medal as part of the Women's 4x200m freestyle relay team. She then went on to finish fourth in the 400m freestyle event.
A year later, in front of a home crowd at the 2018 Commonwealth Games, Titmus was dominant; winning three gold medals in the Women's 400m freestyle, the 800m freestyle and the 4x200m freestyle relay, as well as silver in the 200m freestyle.
A fruitful Commonwealth Games campaign headlined a strong calendar year for Titmus, who also earned gold twice at the 2018 World Short Course Championships and once at the Pan Pacific Championships.
At the 2019 World Championships, Titmus took top honours in the Women's 400m freestyle and the 4x200m freestyle relay, whilst also earning silver and bronze in the 200m freestyle and 800m freestyle, respectively.
Ariarne confirmed she was one to watch in Tokyo at the Australian Olympic trials held in Adelaide, where she swam a time of 1:53.09 in the 200m freestyle and 3:56.09 in the 400m freestyle, making her the second faster women ever to swim both events.
Her times also set new Commonwealth records in both the 200m freestyle and 400m freestyle, and narrowly missed the world record by just 0.11 seconds in the 200m.
The 20-year-old will make her Olympic debut at the Tokyo 2021 Olympic Games, where she will compete in the 200m freestyle and 400m freestyle.
