Prepare for an all-time Olympic showdown, with American superstar Katie Ledecky part of a trio of likely medal contenders in the women’s 400-meter freestyle. Ledecky is a two-time medalist in the event, taking gold at the 2016 Rio Games and silver at the Tokyo Games in 2021.

But her quest for an eighth overall Olympic gold — which would put her one shy of tying the record for a women’s athlete — could be thwarted, or at least delayed, by Australia’s Ariarne Titmus or Canada’s Summer McIntosh, both of whom have strong gold-medal potential. Titmus famously beat Ledecky in Tokyo and set the world record in 2023.

The women’s 400-meter freestyle final follows the same event on the men’s side. They will be followed by the women’s and men’s 4×100-meter freestyle relay finals, the latter of which will likely feature U.S. star Caeleb Dressel. He and the relay team will look to defend their gold medal from Tokyo, but could be unseated by challengers Australia or China. Great Britain and Italy are also contenders.

On the women’s side, Australia — the three-time defending Olympic gold medalist in the 4×100-meter freestyle relay — is expected to continue its dominance, but the American team — including veteran Simone Manuel — hopes to improve on a bronze medal finish in Tokyo.
