The author, the host of NPR's "Wait Wait ... Don't Tell Me!" and columnist for "Runner's World," shares stories, advice, lessons, and warnings from his experiences.

Peter Sagal, the host of NPR's Wait Wait...Don't Tell Me! and a popular columnist for Runner's World, shares lessons, stories, advice, and warnings gleaned from running the equivalent of once around the earth. At the verge of turning forty, Peter Sagal--brainiac Harvard grad, short bald Jew with a disposition towards heft, and a sedentary star of public radio--started running seriously. And much to his own surprise, he kept going, faster and further, running fourteen marathons and logging tens of thousands of miles on roads, sidewalks, paths, and trails all over the United States and the world, including the 2013 Boston Marathon, where he crossed the finish line moments before the bombings. In this new book, Sagal reflects on the trails, tracks, and routes he's traveled, from the humorous absurdity of running charity races in his underwear--in St. Louis, in February--or attempting to "quiet his colon" on runs around his neighborhood--to the experience of running as a guide to visually impaired runners, and the triumphant post-bombing running of the Boston Marathon in 2014. With humor and humanity, Sagal also writes about the emotional experience of running, body image, the similarities between endurance sports and sadomasochism, the legacy of running as passed down from parent to child, and the odd but extraordinary bonds created between strangers and friends. The result is a funny, wise, and powerful meditation about running and life that will appeal to readers everywhere.
