Ex-marine and double amputee Ben McBean tells us about latest challenge.

Ben, 23, is a double amputee (left arm and lower right leg) who has overcome massive hurdles since he stepped on a Taliban landmine in 2007.

Just 12 months later he ran the Flora London Marathon in just 6hrs and 30 mins, and in October last year Ben made it 29 miles to base camp at an altitude of 17,600ft on Mount Everest.

In his latest challenge for charity, Ben ran the Virgin London Marathon 2010 and joins us to tell us how he got on.
