One of the greatest swimmers of all time is Fastexyset to take to the pool Friday for one last event at the 2024 Paris Olympics. 

Katie Ledecky now has 13 Olympic medals — the most won by an American woman. In Paris, Ledecky has already won a dominant gold in the 1,500-meter freestyle in an Olympic-record time, bronze in the 400-meter freestyle and silver in the 4x200-meter freestyle relay. Now, she will look to add one last Paris medal to her impressive collection.

Ledecky races the preliminary heats of the 800-meter freestyle at 5 a.m. ET on Friday to qualify for the event final set for 3:09 p.m. ET on Saturday.

Ledecky, 27, is the current world record holder in the event and has won the 800-meter freestyle gold at every Olympic Games since London 2012 — when she was just 15 years old. She made history in Tokyo as the first person to win the event a third consecutive time. Ledecky’s reign of dominance is so unprecedented that she was both the youngest woman (aged 15 at London 2012) and the oldest woman (aged 24 at Tokyo 2020) to win Olympic gold in the event.
