Racing the Clock Running Across a Lifetime

Biologist and accomplished ultra-marathoner Bernd Heinrich turns his scientific lens inward in Racing the Clock, a book that intertwines personal memoir with rigorous scientific investigation. Heinrich explores the complex relationship between running, aging, and the human body, examining the effects of metabolism, diet, and exercise on the aging process. He investigates why some bodies age differently and the extent to which individuals can influence these changes through activity.

Drawing on a lifetime of research and personal experience as a long-distance runner, Heinrich delves into how our bodies adapt and change over time. He offers insights into working with, and potentially overcoming, age-related transformations, connecting these observations to broader principles of evolution, health, and well-being. The book culminates with Heinrich's own journey towards what he intends to be his final race, a fifty-kilometer event at the age of eighty.
