Alastair Humphreys is an English adventurer and author whose defining feat took four years: a 46,000-mile bicycle journey around the world. It is the kind of undertaking that sounds invented until you sit with the numbers, and it earned him recognition as a National Geographic Adventurer of the Year in 2012.
What makes Humphreys interesting, though, is what he did next. Rather than chasing ever bigger expeditions, he championed the microadventure – the short, local, accessible trip that fits around a job and a family. The idea has genuinely shifted how many Britons think about the outdoors, and it made him something rarer than an adventurer: a useful one.
