These aren’t cycling, but for anyone who likes books about long journeys I can heartily recommend:
1. ‘The Long Walk’ by Slawomir Rawicz. A ‘based on a true story’ book about escaping from a Siberian WW2 gulag on foot to India. This is personally very moving for me as my grandfather actually did escape from a gulag and wind up, via Karachi, in Britain and the RAF (sadly, how he actually did it has been lost in the mists of time).
2. ‘A Time of Gifts’ and ‘Between the Woods and the Water’ by Patrick Leigh Fermor. A totally different, absolutely joyous travelogue about a young man who travels on foot from London to Constantinople in the early/mid 1930s, across a Europe that is half aware of the coming storm, and half still a romantic tapestry of ancient castles, deep woods and Counts and Countesses.
