This is the story of a 6,500-km / 4,000-mile trail of footprints from Istanbul to Edinburgh, via moor, plain, and mountain, through storms and cities, joys and agonies, by mid-day sun and dark of night. I hope you find it interesting, and maybe even useful; and if, like me, you find yourself imagining further chapters, please see Walk the West and A Través del Sur, which describe my subsequent walks across North and South America.
