Prince Harry is to battle extreme temperatures in a test of punishing physical endurance by joining a team of wounded military servicemen who are trekking to the North Pole.

He will join the expedition for a five-day stint as the team walk across the frozen Arctic in temperatures as low as -60°C.

Prince Harry will be tracked for a documentary to be screened later this year on BBC1, tentatively called North Pole Warriors.

The full expedition is expected to take around four weeks and will cover up to 200 miles.

Members of the team will be pulling their equipment on sledges, each weighing more than 100kg.

Prince Harry – patron of the Walking With The Wounded charity – will join the group at their base camp in Longyearbyen, northern Norway, tomorrow, to begin training.

His fellow travellers will include four wounded soldiers seriously hurt during active service, two of them amputees.

Prince Harry will leave the group on April 5, to return to the UK for further military training as he qualifies as an Apache Helicopter pilot with the Army Air Corps.

His team consists of Afghanistan veterans Captain Martin Hewitt, 30, Captain Guy Disney, 28, Sergeant Steve Young, 28, and Private Jaco Van Gass, 24.

Accompanying them will be expedition leader Inge Solheim, guide Henry Cookson and charity founders Edward Parker and Simon Daglish.

Prince Harry said: “What the Walking With The Wounded North Pole Team is undertaking is an enormous adventure of the most challenging order.

“I’m delighted that their training has been going well so far, and that they feel prepared for the task ahead.”

He added: “The funds that Walking With The Wounded will – I hope – raise, with the public’s support, will make a life-changing difference to injured servicemen and women from our Armed Forces, re-training and re-skilling them for their own challenging futures.”

The team will face gruelling terrain plus ice and wind storms.

The executive producer of the BBC1 documentary, Alison Kirkham, said: “Bringing the stories of these incredibly brave soldiers to a BBC1 audience is a privilege.
