About
In Why We Run, biologist, award-winning nature writer, and ultra-marathoner Bernd Heinrich explores a new perspective on human evolution by examining the phenomenon of ultra-endurance and makes surprising discoveries about the physical, spiritual -- and primal -- drive to win. At once lyrical and scientific, Why We Run shows Heinrich's signature blend of biology, anthropology, psychology, and philosophy, infused with his passion to discover how and why we can achieve superhuman abilities.
