On Day 11 of the Rio Olympics, Simone Biles is seeking a fourth Olympic gold, one of 28 to be handed out.

Her challenge Tuesday comes in the floor exercise, where the American gymnast will try to fend off teammate Aly Raisman. Biles has already earned three golds – and a bronze Monday night when she wobbled during the balance beam final.

On the men’s side, Oleg Verniaiev leads on parallel bars while Epke Zonderland of the Netherlands will try to defend his Olympic high bar title.

Five gold medals are up for grabs in track events, including women’s 1500 meters and discus, and men’s high jump, triple jump and 100-meter hurdles.

At the Rio velodrome, the British team is hoping for big things. Jason Kenny is going for his third gold in Rio, this time in the keirin; Katy Marchant and Becky James are in the individual sprint and Laura Trott is favored to defend her title in the women’s multi-event omnium.

Semifinals are taking place in women’s soccer and in men’s and women’s beach volleyball; knockout play begins in women’s basketball, with the U.S. facing Japan; and the men are swimming in the open ocean off Copacabana beach.
