High in the mountains of southern Africa, 15 swimmers compete in one of the most extreme-and chilling-races on earth. With no wet suits or protection, they swim one kilometer in water that is cold enough to kill them. For these athletes, it’s not just a battle to the finish, every stroke is a battle to stay alive.
Tune in to "That's Amazing" every Sunday at 9pm on The Weather Channel.
