Michael Phelps may be the greatest swimmer of all time, but is he as great as a Great White shark?
The Discovery Channel plans to answer that question for their annual Shark Week. Vice reports that the network is planning to pit Phelps against the beast in a special event on July 23.
Phelps, who holds 39 world records and 23 gold medals, will try his swimming speed against the shark in a details-undisclosed swimming battle. Phelps recently shared a photo on Instagram of a shark with the caption, "I was able to do something that I had always wanted to do. Be in a cage and dive with great White sharks!!"
Discovery is billing the upcoming race as a must-see event.
"An event so monumental no one has ever attempted it before," the network's statement says. "The world's most decorated athlete takes on the ocean's most efficient predator: Phelps v. Shark — the race is on!"
Shark Week begins on July 23 on Discovery Channel.
