John Davis, PhD in Biomechanics and elite marathon coach, dives deep into the secrets of marathon training. He discusses physiological resilience, highlighting how it differentiates marathon performance from shorter events. John explores the causes of the notorious 'marathon fade' and how specific training intensity and recovery can enhance performance. Listeners learn about depletion workouts, the impact of fueling on endurance, and practical tips for structuring workouts to build resilience. A must-listen for all aspiring marathoners!

ANECDOTE

Downhill Neglect Cost Fast Marathon Finishes

  • John described misplanning for a downhill race (CIM) while training on flat roads in Minneapolis.
  • His athletes faded after mile 16 until he added downhill-specific sessions and they improved.

Resilience Is A Fourth Performance Metric

  • Physiological resilience measures how fast VO2max, running economy, and steady-state max deteriorate during long efforts.
  • It's the key reason some runners strong at shorter distances still fade in marathons.

Different Mechanisms Underlie Slow Fades vs Walling

  • Slow fades in marathons reflect gradual physiological deterioration; sudden 'walls' are more likely fueling failures.
  • Both mechanical muscle damage and central sensing of fuel influence the pattern of slowdown.
