In reply to Sharp:
Put me back on my bike is excellent, as is The Crooked Path to Victory by Les Woodland (a complete history of doping in cycling).
As a how to... Simon Doughty's The Long Distance Cyclists Handbook is great
.....Barring Mechanicals, an audaxer tells his story of (the four yearly) London Edinburgh London, has an excellent introduction. but imagine reading a book about riding 1400km in 100-ish hours. if the distance and place names were ommited then it would be significantly shorter. My friend but it for me as inspiration for LeJOG. what it has done, is served to illustrate just how boring you can become when telling friends about your last adventure.
two non-cycling books i'd recommend are No Way Down (K2 disaster) and A Voyage for Madmen (the first round the world yacht race)
