Prince Harry 'to trek across the Sahara Desert' for Walking with the Wounded charity

Prince Harry has reportedly set himself the grueling challenge of walking across the Sahara Desert to raise funds for the charity Walking With The Wounded. The 31-year-old is said to be taking part in the Marathon des Sables in Morocco in 2017 which comprises a 156-mile walk in 100F heat while carrying a heavy survival kit.

Last year, one of Harry's trusted aides completed The Marathon des Sables, which is described as "the toughest footrace on Earth".

The Prince previously joined injured veterans on treks around Britain and to the South Pole in 2013. Walking With The Wounded organiser Victoria Nicholson accompanied the daring royal along with wounded veterans Ibi Ali and Mark Wise.

An insider told Mail Online: "Harry plans to register for the 2017 race. Victoria completed the race with veterans who had lost an arm and one conclusion they came to was that it would be almost impossible to complete with a veteran who has a leg or lower body injury. They will bear this in mind when they decide the teams.'

The race takes six days and entrants are only able to have a few hours sleep each night.

Prince Harry's friend Ben Fogle, who completed the race in 2004, said he is certain the young royal has the survival skills and the physical stamina to endure the walk.

He said: "I am not worried about him because he is physically very fit and anything in the desert is a busman's holiday for him – he has seen active service in the desert, after all. If he asks for advice I'd say you look after your feet – the sand gets everywhere!"
