Simon Biles will again be one of the highlights of the 2024 Olympics today as she tries to win the vault event for her third gold medal in Paris.

Sha’Carri Richardson will go for her first Olympic medal in the women’s 100 meters, while in the pool Katie Ledecky will look to add another gold to her collection in the women’s 800-meter freestyle.

The U.S. women’s soccer team will be in action as well, taking on Japan, as will the U.S. men’s basketball team against Puerto Rico.

Here’s a guide of what to watch:

Gymastics

After winning gold in the individual all-around and helping the U.S. dominant in team all-around to burnish her legacy, Simone Biles will go for a third gold this Games in the vault final.

Biles is among the favorites again but should face a tough challenge from Brazil’s Rebeca Andrade, the defending Olympic champion in the event.

Medal for Sha’Carri Richardson?

Richardson missed the Tokyo Games because of a positive marijuana test at the 2021 U.S. Olympic Trials but now will get her chance to win a medal in the women’s 100 meters.

Richardson is the reigning world champion in the event, which could also include three-time Olympic gold medalist Shelly-Ann Fraser-Pryce of Jamaica.

Swimming

With a victory in the women’s 800-meter freestyle, Katie Ledecky would join fellow American Michael Phelps as the only swimmers — of any gender and from any country — to win four gold medals in the same event.

Ledecky will be an overwhelming favorite. She is the world record holder at the distance with a time of 8:04.79.

Women’s soccer

The U.S. will take on Japan in the quarterfinals of women’s soccer.

The Americans won all three group-stage games for the first time since 2012 to finish atop Group B. Japan, the 2012 Olympic silver medalists, won Group C. The U.S. won the gold in 2012.

Men’s basketball

The U.S. men’s basketball team goes for its third consecutive victory when it faces winless Puerto Rico.

It will be the final group-stage game for the U.S., which is seeking the top seed ahead of the knockout rounds.

Women’s tennis

Either China or Croatia will earn its first singles gold medal in Olympic tennis with Zheng Qinwen playing Donna Vekic in women’s final.
