Katie Ledecky, 16, finished her first world championships with her fourth gold medal (in as many events) and her second world record. She followed up her Olympic title in the 800 freestyle with the world title in the event, coming back to beat Denmark’s Lotte Friis in 8:13.86.
Ledecky is the second woman to sweep the distance freestyles at a world championships, joining German Hannah Stockbauer, who did it in 2003 at the same Palau Sant Jordi pool in Barcelona.
