Michael Phelps Ends Retirement

Looks to Rio

Michael Phelps resumed training in fall 2013 and reentered the U.S. drug-testing program. After six months, he is now eligible for competition by the U.S. Anti-Doping Agency.    

On April 24 to 26, Michael Phelps will compete for the first time since the London Olympics. According to the Associated Press, the 22-time Olympic medalist will swim the 100-meter butterfly and the 50- and 100-meter freestyle events at the Arena Grand Prix in Mesa, Arizona. The meet is likely a first step toward the 2016 Games in Rio.

"I think he's just going to test the waters a little bit and see how it goes," said Phelps's coach, Bob Bowman. "I wouldn't say it's a full-fledged comeback."

Phelps, who turns 29 in June, could conceivably compete for at least another decade. After all, five-time Olympic swimmer Dara Torres took home two silver medals at the Beijing Games at the age of 41.
