The Adventure Show travels to the Isle of Arran for a bike race with a difference - the Grinduro. With four intense timed sections over road, gravel and dirt, the spectacular 83-kilometre course has attracted people from across the world. This is an event designed for all-round bike enthusiasts determined to have a unique experience. Also in the programme, a walking group from Glasgow show that regardless off, Scotland's mountains, glens and forests make for a perfect day out. Plus the brand new challenge of loch bagging, and proof that the demanding sport of orienteering is accessible to people of all abilities.
