Prince Harry Trains for South Pole Expedition by Spending 24 Hours in Ice Chamber

Royal will compete against Alexander Skarsgård in 208-mile charity trek this November

Watch out, Alexander Skarsgård–Prince Harry's not playing around.

The 29-year-old royal spent 24 hours in a Cold Chamber training exercise as part of his preparation for the upcoming Walking With the Wounded South Pole Allied Challenge. Alongside four teammates, all of which were injured in Afghanistan, Harry practiced setting up camp in sub-zero temperatures with wind speeds up to 45 miles per hours.

When asked what was the worst part about the Sept. 16 training exercise, Harry quipped, "Going in!"

Teammate Kate Philp said having the prince as part of the team was "great."

"He's experienced at this, having spent some time at the North Pole also," she said. "He knows what he's doing. He's got his military training, and it's very, very easy, so he's a good extra pair of hands."

And does Harry actually do the hard work alongside his teammates?  "Oh God, absolutely," said Kate. "We wouldn't let it be any other way, and he wouldn't want it to be any other way."

Let's hope Alexander's training for this November, too! But no matter who comes in first, everybody comes out a winner in one respect, as funds raised from the trek benefit wounded servicemen and women from the U.K., Canada, Australia and the United States.
