Should we consider slowing down to Zone 1 for most of our training? Returning guest and Brad Kearns, co-author of Born to Walk: The Broken Promises of the Running Boom, and How to Slow Down and Get Healthy–One Step at a Time, and long-time advocate for rethinking training principles.
Building on our previous conversation with Mark Sisson, Brad explores the misunderstood world of aerobic conditioning. We discuss what elite athletes like Eliud Kipchoge are getting right—and what most recreational runners are missing—by focusing on slow, low-intensity efforts. Brad challenges the hype around Zone 2 training and shares insights on polarized training, resilience, and the surprising value of walking. Brad highlights the importance of building an aerobic base, using zone one training to prevent injuries, and balancing high-intensity workouts with sustainable practices. He also discusses how outdoor adventure sports can foster a deeper connection to nature and improve overall health. With insights into training philosophy and the value of recovery, this episode offers actionable advice for runners of all levels.
