This month's programme covers the OMM - the original mountain marathon - in Highland Perthshire. The first multi-day event of its kind and to many competitors, still the best. A test of endurance, navigation and willpower where competitors need to carry everything they need on their back.
Also, Deziree Wilson joins 30 teams as they hurtle down the Caimgorm ski road in hand-made carts powered only by gravity. Cameron McNeish walks through one of his favourite Scottish glens and discovers the secret of taking the perfect photograph.
