Everyone needs a boost to power through those first steps in the morning or those last steps of a grueling race. And there's no better motivation than hearing from people who have changed their lives through running or walking. The benefits to your physical and mental health from hitting the road or the trail are boundless. In these pages you'll meet men and women who have run or walked off hundreds of pounds, who've conquered injuries, depression, or anxiety, who've made friends, repaired relationships, switched careers--all through the miracle of getting outside and moving their bodies. As ultramarathoner Dean Karnazes says, "Getting out there creates camaraderie, confidence... and calm."

This new collection is also filled with stories from people who have not only done "good" for themselves, but have also raised money for good causes through everything from 5K races to 100-mile ultramarathons. Prepare to be inspired--to do some good for yourself and for others
