Michael Phelps, Swimming, USAThe most decorated Olympian of all time feels he still has something to prove. After his historic eight gold medals in 2008, Phelps struggled to find a life outside the pool. While his body carried him to six more medals in 2012, his mind wasn’t in it. He was arrested for drunk driving in 2014, leading to a stint in rehab––and a renewed sense of purpose. “I tried to bite off more than I could handle in 2012, but I want to be here now,” Phelps says. Now engaged, with a nearly 3-month-old son, Phelps sees Rio as a chance to bring his soul back to swimming; he’ll race in the 100-m and 200-m fly and the 200-m individual medley as well as some relays. Expect these Games to bring his storybook career to a fitting close. —A.P.
