Cycling is Britain's biggest boom sport and nowhere is the boom more evident than on the road: once seen as the preserve of serious racers, the road bike has recently found a new lease of life due to the popularity of challenge rides and Sportives. It is now possible for cyclists of all abilities to ride a well marked, well marshalled event just about any weekend of the year, usually based around one, two or sometimes as many as ten fearsome hills. For the first time, here is a pocket-sized guide to the 100 greatest climbs in the land, the building blocks for these rides, written by a cyclist for cyclists. From lung busting city centre cobbles to leg breaking windswept mountain passes, this guide locates the roads that have tested riders for generations and worked their way into cycling folklore. Whether you're a leisure cyclist looking for a challenge or an elite athlete trying to break records stick this book in your pocket and head for the hills.
