Katie Ledecky swims into history with 800 freestyle victory at the Paris Olympics

NANTERRE, France — Katie Ledecky capped another stellar Olympics by becoming only the second swimmer to win an event at four straight Summer Games, holding off Ariarne Titmus to win the 800-meter freestyle Saturday night.

It was Ledecky’s second gold medal in Paris and ninth of her remarkable career, which marked another milestone. She became only the sixth Olympian to reach that figure, joining swimmer Mark Spitz, track star Carl Lewis, Soviet gymnast Larisa Latynina and Finnish runner Paavo Nurmi in a tie for second place.

The only athlete to win more golds: swimmer Michael Phelps with 23.

Ledecky went faster than her winning time in Tokyo, touching in 8 minutes, 11.04 seconds. Titmus, the Australian star known as the “Terminator,” was right on her shoulder nearly the entire race, but Ledecky pulled away in the final 100.

Titmus, who beat Ledecky in the 400 freestyle, settled for silver at 8:12.29. The bronze went to another American, Paige Madden at 8:13.00.

Phelps had been the only swimmer to win the same event at four straight games, taking gold in the 200 individual medley at Athens, Beijing, London and Rio de Janeiro.

Now he’s got company.

Ledecky claimed her first gold with a surprise victory in the 800 free as a 15-year-old at the 2012 London Games. She has dominated the grueling race ever since.
