Ledecky won gold on Saturday night in the 800m freestyle for the third consecutive Olympics, cruising to victory with relative ease. She finished with a time of 8:12.57, touching the wall 1.26 ahead of the runner-up.
Australia's Ariarne Titmus came in second with a time of 8:13.83, while Italy’s Simona Quadarella came in third at 8:18.35.
