When Vybarr Cregan-Reid set out to discover why running means so much to so many, he began a journey which would take him out to tread London's cobbled streets, the boulevards of Paris, and down the crumbling alleyways of Ruskin's Venice. Footnotes transports you to the deserted shorelines of Seattle, the giant redwood forests of California, and to the world's most advanced running laboratories and research centers to discover more about the history of the places we know and how we use them. Drawing on debates in literature, philosophy, biology, and neuroscience, this liberating and inspiring book reminds us why feeling the earth beneath our feet is a necessary and healing part of our lives
