All eyes will be on Rio this weekend, as an Olympic legend takes his (likely) last lap in the pool.
Michael Phelps will compete in what is expected to be his final Olympic event on Saturday (Aug. 13), during the men's 4x100 medley relay final.
But that's not the only must-see event on tap over the next three action-packed days in Brazil.
U.S. swimmer Katie Ledecky also has a chance to add yet another gold medal to her record-breaking run, as does Jamaican sprinter Usain Bolt, when he laces 'em up for the men's track & field 100M final on Sunday.
