Hal Koerner's Field Guide to Ultrarunning: Training for an Ultramarathon, from 50K to 100 Mil

Simple but well written by a giant and legend. It never gets pretentious nor is it a book for the pros only. Will treasure this for years.

Excellent book! It contains all the essential, important, and accurate information. It is also written in a very engaging way. I really enjoyed it!

Having bought two previous books on "Ultra Running" and been very unimpressed, I have to say this one is very good. It covers everything you will need to know when progressing from Marathon to 50km, 50miles,100km and 100miles. There are training plans for each of these distances. The book is written in a way that inspires and gives confidence along with useful and detailed advice on everything for gear, nutrition, non-running training, injuries, treatment and prevention, race day tips, and training. Each topic is broken down into sub paragraphs, clearly written, often in an humorous way. If you are thinking of, or doing an Ultra Marathon - this is the only book you will need.

Tiene toda la información necesaria para iniciar en el mundo del ultra maratón, las descripciones y explicaciones son muy amenas.

This arrived well packaged and several days before the expected delivery date. The book is short, concise, and easy to read. I love it! I have not run a 50k yet and needed direction on where to start/ how to train. This really lays out a firm foundation for success and highlights many points I never would have thought of. I feel like I can now plan and train properly and have the confidence that I can reach my goal.
