The case for Ian Thorpe
The 'Thorpedo', the finest middle-distance freestyler of his generation and a national hero in Australia. Thorpe won five Olympic gold medals and 11 world-championship titles, dominating the 200m and 400m freestyle and repeatedly lowering the 400m world record toward the 3:40 barrier. At his home Sydney 2000 Games, aged 17, he won the 400m freestyle in world-record time and anchored a stunning relay victory over the United States. At the 2001 Fukuoka World Championships he won six gold medals. Renowned for his size-17 feet, immense reach and metronomic stroke, Thorpe combined precocious success with genuine longevity across two Olympic cycles, and remains, statistically and stylistically, one of the most complete freestylers the sport has produced.
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.
