'In Three Months I Climbed the Highest Peak in Every County in Britain. Nutty... But So Much Fun.' Swapping the nine-to-five grind for the freedom of the great outdoors, Jonny Muir set off on a 5,000 mile cycling and walking odyssey. His mission? To visit the summit of the United Kingdom's 92 counties - in 92 days. Never mind unexploded shells in Yorkshire, biting bugs in the Cairngorms or the gruelling task of climbing the equivalent of 14 Everests, 'The Heights of Madness' is a celebration of our homeland's high places.
