WATCH: Michael Phelps races great white shark ... sort of

Michael Phelps may be fast, but apparently not as fast as a great white shark.

In Discovery's highly anticipated Shark Week special "Phelps vs Shark: Great Gold vs Great White," the 28-time Olympic medalist wore a special wetsuit and monofin to take on a great white – well, sort of – in a 100-meter race.

Unfortunately for fans, Phelps, with a time of 38.1 seconds, lost by 2 seconds. But that wasn't the biggest disappointment: Instead of facing a real shark, Phelps was shown alongside a computer simulation of a great white. The shark's "time" in the race was based on speed data collected by scientists.

Fans were not amused.
