In the middle of winter, with 17 hours of darkness, 500 competitors head north of Inverness for one of the world's toughest mountain bike races - the Strathpuffer 24 hour marathon. And once again, this year conditions are testing as we follow the hardiest of competitors - the solo riders. Also in this month's Adventure Show, we'll be discovering the easy way to carry all your kit on a long distance bike ride. Cameron McNeish and Deziree Wilson will be heading into the hills to check out the latest gear that's available. Plus we'll be joining a remarkable woman whose cerebral palsy hasn't deterred her from following a life of adventure.
