The Adventure Show heads to the north west for a 90-mile cycling event. The Bealach Mor includes the biggest road climb in the UK, with 2,000 feet of ascent in just six miles. In another tough challenge we join one man on his attempt to become the first blind man to climb the Old Man of Hoy in Orkney, and we join Cameron McNeish as he explores the Pentland hills just south of Edinburgh.
