The 2024 Summer Olympics swimming events are underway on the first day of full day of competition in Paris, and Katie Ledecky will be in the pool for the first time in Paris as the first swimming medals are set to be won at París La Défense Arena.
The Women's 400m Freestyle on Saturday sets up as the Race of the Century.
Ledecky will match up against her main rival, Australia's Ariarne Titmus, with Canada's Summer McIntosh in position to win gold if either of the previous two Olympic gold medalists falters.
Ledecky finished first in the Women's 400m Freestyle Prelims earlier on Saturday.
