If you have legs, or a bicycle, or indeed both, you are going to love this book. Chaps, no matter how old or how fat or otherwise incapacitated you are, if you haven’t already received it for Father’s Day the chances are it’s coming your way this Christmas. Ladies: if you are a fell-runner, a hill-walker or a budding Victoria Pendleton, pop this into your backpack or saddlebag with your energy bars and your old Ordnance Survey.
