And on the fifth day, he rests ... Sort of.
For the first time since the competition began in earnest at the Olympics, Micheal Phelps will not be swimming for a medal.
Don't worry, you will still see him on NBC's prime-time coverage Wednesday night here in the States, with the 200 individual medlay semifinals. As the NBC broadcasters pointing out in Tuesday night's telecast, all Phelps does is eat, swim and sleep. And we predict he might be carrying the flag at the closing ceremonies.
He already has five gold medals to bring his record career total to 11. He also has some more work to do over the next few days.
