Women’s swimming has never seen an athlete dominate on the level Ledecky has. The then 15-year-old was a revelation during the 2012 London Olympics, taking home a gold medal in the 800-meter freestyle. She followed up that performance with four more golds in Rio de Janeiro four years later. In total, Ledecky has broken 13 world records over her short career.
