Well after his South Poole Trek was over and he reunited with girlfriend Cressida Bonas, a clip of Prince Harry was released with the royal admitting that he was "terrified" about his upcoming polar journey.

According to E! News, in the preview for the upcoming ITV documentary "Harry's South Pole Heroes," the 29-year-old royal's Antarctica charity race, Walking with the Wounded is filmed and at one point Harry admits that he is scared about making the 200-mile journey in sub-zero temperatures.

Cressida Bonas boyfriend revealed, "I'm terrified for myself, to be honest-hugely daunted."

One of the heirs to the throne admitted, "I don't want to let the side down through fitness or injuries or anything like that.

"There's a lot of pressure on everybody involved, so I've just got to get it right...It's not just about fitness, it's about knowing exactly what you can and can't do."

The Prince then begun to speak of his teammates who are injured servicemen. He said, "For me, it's bigger than just these guys."

He continued, "We're trying to raise money but also to raise awareness for the fact that the injuries they've sustained they're going to carry for the rest of their lives."

Despite his nerves Prince William's little brother took some time to acknowledge the Arctic beauty surrounding him.

Prince Harry said, "Just look how cool it is," adding. "It's amazing. It's ridiculous that a place like this should exist. One of the few places on earth that hasn't been screwed up by humans."

Harry's documentary is set to premiere this Sunday on ITV.
