Olympic gold medallist and world record holder Michael Phelps is set to go head to head against a great white shark for Shark Week 2017.

Shark Week 2017 starts on July 23, and the Olympian won't really be swimming next to a great white but instead testing speed against various other shark species, Yahoo reports.

The fierce underwater predators can reach up to speeds of 25 to 30 mph, whereas Phelps can reach up to 6mph.
