Michael Phelps to Quit Swimming

The record breaking Olympian has confirmed that he will retire from professional swimming at the end of the London games.

For Michael Phelps, 22 Olympic medals, 18 of them gold, really is enough, as he confirmed that his swimming career is over.

In an interview with Bob Costas on NBC, Phelps said he has no regrets about his career. "I can look back at my career and hang my suit up and say I've done everything I wanted to do," Phelps said.
