Swapping the nine-to-five grind for the freedom of the great outdoors, Johnny Muir set off on a 5,000-mile cycling and walking odyssey. His mission? To visit the summit of the United Kingdom’s 92 countries—in 92 days. Never mind unexploded shells in Yorkshire, biting bugs in the Cairngorms, or the grueling task of climbing the equivalent of 14 Everests, The Heights of Madness is a celebration of Britain's high places. If you’ve ever wondered what the highest point in Norfolk is, or why 500,000 people climb Snowdon every year, this is the book for you.
Jonny Muir’s early wanderings took him over the Lickey Hills, before he graduated to the giddier heights of the Lake District and Snowdonia.
