Training for the Uphill Athlete
Despite the size of the book, this is a quick read. Its filled with sprawling mountain vistas and side bar advice from elite athletes in the field, all of which is designed to motivate the hell out of you. It covers similar ground to Steve Magness’ Science of Running, with more emphasis on vertical trail races and ski mountaineering, which requires some tweaking to the general runner’s training plan. Not a beginner’s book. I would recommend Krissy Moehl’s Running Your First Ultra or Hal Koerner’s Field Guide to Ultrarunning if you’re new to the sport. Actually, just start with Powell’s Relentless Forward Progress.
