Please note: This is a companion version & not the original book. Sample Book Insights: #1 The three sports of mountain running, skimo, and ski mountaineering are complementary in most of the demands made on the body. They can be combined for training. Where they differ, you’ll learn how to apply different training techniques. #2 The book is designed to be used as a reference manual to guide your training over many seasons as you apply what you have learned. Each section is supported by the preceding ones and as such supports the subsequent parts.
