Arctic dawn for charity trek Harry
Prince Harry has said sleeping in a tent in the Arctic was not something he had ever planned on doing - but it was "nice" to feel the cold.
As he packed up his kit and jumped up and down to stay warm, the 26-year-old was asked what it was like to sleep in temperatures as low as minus 25C.
He said: "Is that all it was, minus 25C? It felt a lot colder than that in there. It was good."
The prince spent Wednesday night in a tent with Inge Solheim, who will be leading an expedition of wounded servicemen to the North Pole, and Henry Cookson, who has been training Harry for when he joins the trip for the first five days.
The prince joked: "There are things that happened in that tent I never want to speak of ever again."
Harry is patron of the Walking With The Wounded charity, which wants to raise £2 million to help injured servicemen find work and peace of mind after they leave the armed forces.
He has spent the last three days with the team who are making the trek, made up of four wounded soldiers, two charity co-founders and Mr Solheim.
Harry, third in line to the throne, said the rest of the day will be spent getting ready.
"I think we're preparing for leaving, which is going to take a while," he said.
Asked how he was feeling about the trip, he said: "Good. I think it got down nice and cold last night. It was nice to feel it, but it's going to be different. Here, at least we're on ground. Spending the night on frozen ice wasn't something I had planned on doing, but everyone else is doing it, so I might as well do it as well."
