Harry's Arctic Heroes is a BBC documentary, capturing a special expedition undertaken by a team of wounded servicemen as they attempt a gruelling 200 mile charity trek to the North Pole.With no back-up vehicles or doctors, the team pull all the equipment and supplies they need for the duration of the expedition over the toughest terrain in the world. They face a constant battle with ice and wind storms that would test the most able-bodied of Arctic explorers.Prince Harry is the patron of Walking With The Wounded, the charity that organised the expedition. He joins the team on the ice for the first leg of the expedition when for a week he pulls his own sledge, sharing tent-pitching and food preparation duties and faces the same gruelling Arctic conditions as his fellow servicemen.
