When junior doctor Stephen Fabes set off on a round-the world adventure he wasn’t exactly best prepared. In fact, so out-of-shape was he, that the first leg of his journey consisted of a paltry 14 miles from London's Embankment to a guesthouse in Bexleyheath. Six years later he’d succeeded in crossing six continents and tallying an impressive 53,568 miles of bicycle travel. Signs of Life, To the Ends of the Earth with a Doctor is his book documenting that extraordinary feat.
