The case for Alexander Popov
The 'Russian Rocket', the greatest pure sprint freestyler of the 1990s and a technician of legendary smoothness. Popov won the 50m and 100m freestyle at back-to-back Olympics, Barcelona 1992 and Atlanta 1996, four individual golds and nine Olympic medals in total, along with around six world-championship titles across a long career. Remarkably, he was stabbed in a Moscow street incident in 1996 yet returned to competition and set a 50m freestyle world record of 21.64 in 2000. Coached by Gennadi Touretski, Popov swam with a famously long, relaxed stroke that let him dominate the sprints for a decade, and he remained competitive into his early thirties, an unusual feat for a sprinter, winning world titles in 2003.
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.
