Along the way, he breaks down common misconceptions, highlights what actually matters, and provides practical, step-by-step strategies you can apply straight away. If you’ve ever felt confused by conflicting advice or stuck in an injury cycle, this episode will help you cut through the noise and run smarter. 🧠 Questions Covered How do you safely transition to zero drop / minimalist shoes (especially with a neuroma)? What are the best exercises for ITB syndrome—and are exercises even the priority? Do you need a VO2 max test to truly train in Zone 2? What’s the safest way to introduce sprint training? Why do your calves (soleus) feel like they’re burning early in runs—and what can you do about it? 🔑 Key Takeaways Zero Drop Transition Transition gradually—this is non-negotiable Start with walking / strength work before running Introduce running in small doses (5–10 minutes per run) Build volume slowly (~10% per week) Monitor for warning signs: calf tightness, foot pain, Achilles stiffness ITB Pain (What Actually Matters) The cause is usually load + mechanics, not just weakness Common triggers:Downhill running Narrow or crossover step width Cambered surfaces

First line of treatment:Modify training load and mechanics

Strength work (secondary but helpful):Step-downs Crab walks Hip hikes Single-leg control work

Zone 2 Training (Do You Need Lab Testing?) VO2 max testing = gold standard, but not essential Most runners can rely on:Effort (RPE) Conversation test

True Zone 2 should feel:Sustainable for long durations Minimal fatigue buildup “Could do it all over again” effort

Introducing Sprint Training Start with strides, not all-out sprints Structure:Gradual acceleration (15 sec) Short peak speed (8–10 sec) Full recovery (1–2 min)

Progression:Start with 4 reps at ~75% effort Build to 6–8 reps at ~90–95% effort

Keep it controlled and progress gradually Burning Calves (Soleus Overload vs Something Else) The soleus handles very high loads during running Common overload factors:High intensity or hills Minimalist footwear Rapid training increases

But… consider another possibility:

👉 Compartment syndrome Clues it might not be “just tight calves”: Burning sensation early in runs Bilateral symptoms Long-standing issue despite rehab Forced to stop rather than push through Helpful strategies: Longer, more gradual warm-ups Walk/run approach Avoid sudden intensity spikes Let symptoms settle before continuing
