Ryan Lochte, U.S. swimming

What he did in London: Won five medals including golds in the 400 IM and the 4x200 freestyle relay What's next: Even though Lochte, 28, is a year older than Phelps, 27, he has no intention of retiring before the 2016 Rio Games. That doesn't mean that his focus will be solely on swimming the next four years though. Lochte says he wants to appear on Dancing with the Stars and he's open to other TV, media and endorsement opportunities that pop up. "I'm so used to being out there in a Speedo, that being on display is nothing new," Lochte told SI.com recently. "I'm looking forward to all of it."
