Also in this month's Adventure Show, we're joining a remarkable man who's determined that losing two limbs won't prevent him from doing the sports he loves.
And we're off to Patagonia with one of Scotland's most ambitious adventurers as he undertakes a month-long trip in one of the world's most remote landscapes.
