Steve Magness brings a coach's eye and a scientist's curiosity to Science of Running, a podcast dedicated to the intricate details of endurance performance. This isn't just about generic training tips; it's a deep, often challenging exploration of the physiological and psychological principles that underpin running. Each episode dissects topics like periodization, recovery, nutrition, and the mental game, translating complex sport science into actionable insights for runners and coaches alike. You'll hear conversations that question conventional wisdom, examine the latest research, and delve into the art of coaching itself.
