Science of Running

Track and field has incredible athletes, record-breaking performances, and millions of participants. So why is it so hard to follow? Steve and Jon unpack running’s story problem: scattered championships, hidden results, conflicting incentives, training content replacing competition, and a sport that too often makes fans do all the work. They argue for more rivalries, history,…

The Norwegian method has become running’s latest formula. But its value isn’t in blindly copying double-threshold sessions or chasing perfect lactate numbers. Steve and Jon unpack the principle beneath the method: control the effort, create a signal the athlete can absorb, and repeat it long enough to adapt. A conversation about RPE, survivorship bias, individualized…

You don’t need a professional athlete’s schedule to train well. But you do need to stop pretending you can fit everything in. Steve and Jon explain how time-starved athletes can identify what matters, shift priorities across seasons, protect what keeps them in the sport, and resist shortcuts promising four years of adaptation in four weeks.…

Training is only the input. Adaptation is the goal. Steve and Jon explore why the same workout can transform one athlete and bury another and how stress, recovery, nutrition, individual differences, and the messy reality of working with human beings determine what actually sticks. Do us a favor, fill out this coaching survey to help…

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.…
