July 24 (UPI) -- Michael Phelps lost to a great white shark in a 100-meter race Sunday during Discovery Channel's kick off of Shark Week.
In Phelps vs. Shark: Great Gold vs. Great White, the 23-time Olympic gold medalist was given a 1-millimeter-thick bodysuit that mimics the skin of a great white shark along with a monofin in order to even the playing field. Phelps' top speed is listed as 5 mph while a great white can swim up to 25 mph.
