Phelps vs Shark: Great Gold vs Great White

As a kickoff to Discovery's annual Shark Week, Michael Phelps takes his mark for a 100-meter, open-water race off the coast of Cape Town, South Africa.

He doesn't swim side by side (that's too dangerous), and won't divulge exactly how they were paired up. But he strapped on a monofin (a wide fin with pockets for both feet that provides a nice boost in speed) in an attempt to level the playing field.

"In a race, I think my fastest speed was about five or six miles per hour," Phelps says. With the monofin, he estimates he got up to "8 to 10, maybe 12.

Who will be the faster swimmer?

The winner will be revealed on July 23rd at 8:00 pm ET on Discovery Channel's Shark Week.
