Geraint Thomas's inside guide to twenty-five of the greatest cycling climbs in the world. Cycling fans obsess about climbs and big mountains. They love reading about their tests and tribulations and they love to ride them - a cricket lover can never bat at Lord's, or a football supporter score at Wembley, but any rider can take on the challenge of an iconic mountain. There have been fine books about the big climbs before but never from the voice of an elite GC winner, taking you inside what these climbs really feel like, where the attacks come, where the pain kicks in. From best-known big-hitters, via pro-peloton favourites, to the secret climbs Geraint has come to love, and featuring Australia, Belgium, France, the Netherlands, Mallorca and Wales, this is the cyclist's secret manual.
