At 10.41a.m. on a Tuesday morning in September, Mark Mason boards the number 1A bus at Land’s End. Forty-six buses and eleven days later he disembarks at John O’Groats. Along the way he visits everywhere from the village where the internet enters Britain to the urban sprawl of Birmingham (inspiration for the Two Towers in Lord of the Rings). He samples staples of the British diet from curry to the deep-fried Mars Bar, and uncovers countless fascinating facts about his native land – did you know, for example, that Crewe Alexandra football club is named after the wife of Edward VII or that Loch Ness could hold the water from all the lakes in England and Wales?
