Wounded soldier aims to be the first double-amputee to trek to the South Pole

When faced with the tragedy of losing both of your legs, most people would think twice about competing in a physical challenge, but not Duncan Slater - who is tackling one head on.

His latest ambition is to become the first double-amputee to walk to the South Pole, a daunting prospect for even the hardiest of thrill-seekers.

A Sergeant in the RAF, Duncan was serving in the infantry arm in Afghanistan in 2009, when his vehicle was hit by a bomb and he was severely wounded. He broke most of the bones in his body, including his back, when his leg injuries didn't heal, he had to have them both amputated in 2010.

Last year he took part in a cross country cycle from Land's End to John O'Groats to raise money for the RAF Benevolent Fund and Help for Heroes.

He is currently training for the trek in Iceland and in this video he talks about the additional challenges he faces in a cold climate.
