Running is more than just a sport. It is also a magical way to get offline and recover some of the joy that modern life increasingly denies us. In Footnotes, Vybarr Cregan-Reid sets out to discover why running means so much to so many. He embarks on a journey that takes him back to nature and across continents, through fascinating terrains and to the world’s most advanced running laboratories and research centres. He discovers the horrifying history of treadmills, how running makes us more intelligent and even why our bodies look the way they do. Calling upon debates in literature, philosophy and biology to explore our simple desire to run, this book will inspire you to get off the sofa and head for the hills.
