Fit people come home without the summit.

You are not unfit. That is exactly what makes this dangerous. You run, you lift, you ride. Then somewhere around 3,600m, on a day that was going fine, your legs stop answering and the decision gets made for you. The guide is paid. The hut is paid. The flights are not coming back.

This book will not make you fitter. It will tell you, honestly, what you are missing.

It is the thinking behind Train to Mountain, written plainly: what a summit day actually asks of a body, why the descent breaks more attempts than the climb, and how to find out where you stand before you are standing on it.
