We're getting a revealing look inside Prince Harry's South Pole trek.
In a preview for the upcoming ITV documentary Harry's South Pole Heroes, which chronicles the 29-year-old royal's Antarctica charity race with Walking With the Wounded, Harry admits he was scared about making the 200-mile journey in sub-zero temperatures.
"I'm terrified for myself, to be honest—hugely daunted," Harry said. "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."
