Here are the five biggest events you need to keep your eye on Thursday at the Rio Olympics.
Swimming
Men’s 200 individual medley final
The two most decorated male swimmers of all time will close the book on their storied rivalry. Michael Phelps and Ryan Lochte will square off in the 200-meter individual medley, an event in which they finished 1-2 in London four years ago. This will likely be the final time these two compete, as Phelps has said he’s all but assuredly done with competitive swimming after these Games. MORE: Top swimming images.
Gymnastics
Women’s all-around final
In the women’s all-around, Simone Biles is the favorite to win gold and Aly Raisman will be a medal contender. An American woman has won the all-around at the last three Summer Games.
Judo
Kayla Harrison is the defending Olympic champion and she’ll look to repeat in the women’s 78-kilogram (172 pounds) division.
Golf
The men’s tournament gets under way as Matt Kuchar, Bubba Watson and Rickie Fowler represent the United States. The format is 72 holes of individual stroke play.
Field hockey
The U.S. women have been on a roll in Rio, beating Argentina, Australia and Japan. On Thursday the Americans play India although they have already clinched a spot in the knockout round.
