I came across this book at some point about a year ago and thought I'd grab it on a whim - never did get around to writing up a post about it until now.....
In essence, this book is about the techniques for climbing sport routes, going from top roping to on-sighting or red-pointing. It's not a training book for improving your physical performance, but more designed to get you thinking about the other parts of climbing routes. Mental preparation and visualization, strategies for resting and clipping, breaking down the route into sections, etc.
To be honest, this wasn't what I expected when I bought the this book - especially as it came with a foreword from Chris Sharmaaaaaa but as a tool for how to improve your standard of climbing, especially as a beginner or intermediate climber, I can definitely see it's uses.
In short, worth a read if you're looking for some ideas on how to improve on a sports trip at preparing for routes.
