Science of Running

Steve Magness and John Marcus rant about the “recovery industrial complex,” arguing that while recovery knowledge has improved, monetized gadgets can waste money, create psychological fragility, and give a false sense of control—especially as aging brings non-negotiable limits. They emphasize prioritizing foundational recovery: consistent good sleep (the key “canary”), adequate fueling and hydration, and managing…

Steve Magness and Jonathan Marcus discuss an updated approach to summer base building that keeps aerobic mileage as the foundation but adds “spices” year-round to prepare athletes for race demands. Instead of a reductionist focus on aerobic capacity alone, they emphasize integrating neural coordination, mechanical efficiency, and structural tissue resilience to reduce injury risk and…

Steve Magness and Jonathan Marcus discuss the art and science of delayed training effects, arguing that training adaptations are non-linear, hard to quantify, and often misunderstood as quick “return on investment.” They contrast complicated vs complex systems, noting hidden variables and individual response rates that make simple timelines unreliable. Using examples from elite runners, David…

In this week’s episode Steve and Jon discuss injuries as an unavoidable, unpredictable part of running due to impact and eccentric loads, arguing coaching has shifted from “rest and hope” to creative training that maintains fitness without worsening injury. They outline a framework for evaluating injuries by type (bone, soft tissue, metabolic/overtraining, and “WTF” injuries),…

The episode focuses on constraints in coaching: manipulating training and environment to drive physical and psychological adaptation by identifying and widening an athlete’s primary bottleneck. David Epstein recounts Sheila Taormina learning the Theory of Constraints in college, shifting from aerobic volume to strength/power, making the Olympic team, winning relay gold, and later competing across four…

We host Olympian and Norwegian-method innovator Marius Bakken and talk bout the history and principles behind double-threshold training, lactate testing, and “muscle tone” as a key limiter of recovery and performance. Bakken contrasts lessons from coaches like Joe Newton, Peter Coe, and others, emphasizing long-term progression and balancing load with precision rather than uncontrolled intensity.…

Steve Magness and John Marcus continue their peaking series by reframing peaking as maintaining fitness while eradicating fatigue so athletes can express existing fitness on race day, rather than expecting a magical performance boost. They emphasize that peaking is as psychological as physiological: coaches must set realistic expectations that racing will still feel hard, shift…

Steve Magness and Jonathan Marcus discuss how coaches should define a training approach without falling into two traps: having no coherent philosophy by mixing everything, or rigidly copying one system with no flexibility. They argue training must account for environment and reality (altitude, heat/humidity, sea level), athlete population, and psychological constraints, not just physiology or…

Coaching Successful, Part 1: Defining Your Philosophy and Boundaries Steve Magness and Jon Marcus begin a “coaching successful” series by arguing that sustainable high-level coaching depends less on perfect training plans and more on clearly defined philosophy, boundaries, and principles. They discuss the messy identity shift from athlete to coach and warn about “boundary creep,”…

The Illusion of Optimization: Balancing Physiology and Neurology in Coaching In this episode of the Coaching Coaching Podcast, hosts Steve Magness and John Marcus dive into a deep discussion about the complexities of coaching that lie beyond the modern obsession with optimization. They argue that true coaching success comes from a balance between understanding physiology…
