I grabbed this book off of Amazon because I am a runner with budding aspirations to complete an ultramarathon. This book by Michael D’Aulerio is a great primer for such events. It is separated into chapters with each containing practical and useful information. D’Aulerio offers tips on topics such as what to bring to an ultra, how to stay motivated, and how to fuel and hydrate. It is a helpful read that I can see referring to from time to time as I continue to grow as a runner. I highly recommend it for any novice runner who is contemplating an ultra.
