For more than 20 years, the British adventurer Alastair Humphreys roamed the planet. He rowed across the Atlantic, traversed India on foot, cycled around the world. Each hyper-detailed map includes not just roads but footpaths, vegetation and variations in terrain. Humphreys commits to deeply exploring one small segment of his map per week, to getting intimate with his immediate environment, by walking or biking every millimeter. “I wanted it to be serendipitous, not governed by my preferences,” he writes.
