Dr. Gabrielle Lyon
About this episode

Today, I welcome ultra-endurance athlete and world record holder Zach Bitter to The Dr. Gabrielle Lyon Show for an insightful conversation on the extreme physical and mental demands of ultra-marathons. Zach shares his mindset strategies for overcoming the inevitable dark moments in long-distance races, including visualization techniques and the importance of mental resilience in performance.

We also dive into personalized nutrition and training adaptations, as Zach details his transition from a high-carb to a low-carb diet and how it has influenced his endurance, recovery, and overall performance. Our discussion highlights the importance of metabolic flexibility, optimizing fuel sources, and tailoring macronutrient intake based on training intensity. Whether you're an endurance athlete or someone looking to develop greater resilience in life, this episode offers invaluable lessons on mental toughness, strategic nutrition, and the pursuit of excellence.

We discuss:

  • The mental strategies Zach uses to push through ultra-marathons
  • How visualization training enhances race-day performance
  • Transitioning from high-carb to low-carb as an endurance athlete
  • The role of macronutrient cycling in optimizing training and recovery
  • Strength training for runners: Why it matters and how to incorporate it
  • Adapting training for busy professionals: How to maximize results with minimal time
