The case for Simone Biles
The most decorated gymnast in the sport's history and the only one whose skills forced the rulebook to respond to her. Through Paris 2024 Biles holds 41 Olympic and World Championship medals, 30 of them gold: 11 Olympic medals including seven titles, and a record 30 world medals with a record 23 golds. She won six world all-around titles between 2013 and 2023 plus Olympic all-around golds in 2016 and 2024, and did not lose an all-around competition she completed for over a decade. Five elements bear her name across vault, beam and floor, including the triple-twisting double somersault on floor and the Yurchenko double pike vault, valued at 6.4 and never performed in competition by another woman. Her 2024 return, three years after withdrawing from the Tokyo team final with the twisties, added team, all-around and vault golds at 27 — an age at which almost every predecessor had retired.
The case for Vera Caslavska
The only woman to win the Olympic all-around title twice in the modern era before Simone Biles, taking it in Tokyo in 1964 and again in Mexico City in 1968, and the only gymnast to win an individual Olympic gold on every apparatus of her time. She finished with 11 Olympic medals — seven gold and four silver — and world all-around titles in 1962 and 1966, breaking a Soviet monopoly almost single-handedly. Her 1968 campaign is the most extraordinary in the sport's history: she had signed the Two Thousand Words manifesto, fled to the mountains of Moravia after the Warsaw Pact invasion of Czechoslovakia and trained by swinging on tree branches and doing floor work in a meadow, then arrived in Mexico City and won four golds. On the podium for the shared beam and floor titles she turned her head down and away during the Soviet anthem, a protest that cost her the right to travel and compete for years afterwards.
