The case for Dawn Fraser
The pioneering queen of sprint freestyle and one of the toughest competitors in the sport's history. Fraser became the first swimmer, male or female, to win the same event at three consecutive Olympics, taking the 100m freestyle at Melbourne 1956, Rome 1960 and Tokyo 1964. In 1962 she became the first woman to break 60 seconds for the 100m freestyle, and she set 27 individual world records across her career. She won eight Olympic medals (four gold, four silver) in an amateur era before the World Championships existed. Fierce and unruly, she was controversially banned for ten years after a flag-stealing prank in Tokyo, cutting short a career that might otherwise have yielded even more. Her three-in-a-row remains a landmark of durability.
The case for Adam Peaty
The most dominant single-event swimmer of the modern era. Peaty transformed the 100m breaststroke, becoming the only man ever to break 57 seconds and setting the world record at 56.88 in 2019, a mark far ahead of the rest of history. He won Olympic gold in the 100m breaststroke at Rio 2016 and Tokyo 2020, plus a mixed-relay gold, for three Olympic golds, and collected around eight world-championship titles. His 'Project 56' target became a byword for pushing a barrier thought unreachable. Between 2014 and 2021 he was undefeated in the 100m breaststroke at every major final, a streak of dominance rare in any sport. His combination of stroke rate and power rewrote what the event could be.
