The athlete has won the most gold medals of any Olympian ever – famously beating out swimmer Mark Spitz's record of seven gold medals at the 1972 Olympics in Munich.
But Phelps's SI cover is a nice tribute to Spitz. In the portrait, the swimmer strikes an identical pose to an iconic picture of Spitz also adorned with all his medals.
Another milestone for Phelps: This latest appearance on the magazine's cover marks the 23-year-old's fifth cover shot for the magazine, giving him the record for appearing on the cover more than any other swimmer.
