In the middle of winter, with 17 hours of darkness per day, nearly 500 competitors head north of Inverness for Britain's hardest mountain bike race - the Strathpuffer 24 hour marathon. Ice covers much of the course. This year, Dougie is partaking as a solo rider. Lindsay Cannon tries winter surfing. Cameron McNeish experiments with some very small bikes.
