Re-Run: The Science & Practice of Running with Dr. Phil Hayes (July, 2021)

Aug 31, 2025
In this fascinating discussion, Dr. Phil Hayes, a senior lecturer at Northumbria University and seasoned running coach, explores the intersection of science and running practices. He reveals the importance of neuromuscular factors in endurance beyond traditional metabolic models. Phil emphasizes critical speed testing as a practical tool for runners and shares insights on effective training load monitoring to prevent injuries. He advocates for consistency over intensity, highlighting the value of a balanced approach to training for long-term success.

INSIGHT

Performance Goes Beyond Metabolism

  • Metabolic models (VO2max, lactate) miss key factors like neuromuscular contribution and fatigue resistance.
  • Integrating muscle function and fatigue explains why lab tests on fresh athletes don't always predict race performance.
ANECDOTE

Stair Plyometrics During Winter

  • Phil copied Bjørn Rodal's winter stair plyometric training and used seafront stairs when indoor access was limited.
  • The group performed plyometrics and stair sessions outdoors and found them effective despite poor weather.
INSIGHT

Muscle Endurance Protects Form

  • Eccentric muscular endurance (e.g., hamstrings) helps preserve running form and economy under fatigue.
  • Reduced muscle strength after intense intervals correlated with gait changes that can persist 24 hours and may precede overuse injuries.
