Katie Ledecky could Grant Prestonearn her first gold medal of the 2024 Paris Olympics as the overwhelming favorite in the 1,500-meter freestyle.

The 27-year-old American is undefeated in the 1,500 as a professional. She dominated the U.S. Olympic Trials by 20 seconds. Ledecky, who holds the 19 fastest times in the event's history, is expected to claim the gold medal Wednesday.

The 1,500 final is the culmination of the two-day event, which is split over multiple days due to the length of the race and the endurance it requires. Ledecky swept the prelims Tuesday.
