// Masterclass 01 / Breathing
Breathe Better. Run Better.
You get a side stitch at mile two that you've just accepted as part of running. You hit a pace ceiling you can't break through. Your recovery takes longer than it should. You've heard about nasal breathing. You've read about Zone 2. Nobody has watched you breathe. Research shows 91% of competitive athletes display dysfunctional breathing patterns. The problem is near-universal. You just didn't know that yet.
What we cover
- Control under effort. How to keep your breathing rhythmic and effective as the pace climbs. The gear shifts that stop you blowing up at mile two.
- Nasal breathing drills. When to nasal breathe and when to switch. How to extend the pace you can hold nasally so you stay calmer for longer.
- CO2 tolerance work. The physiological piece most runners skip. How CO2 tolerance limits your pace ceiling and how to train it.
- Race-day breathing strategy. A specific protocol for managing breathing under adrenaline. Start line through finish line.
This is for you if you've never had someone watch you breathe under load, or if you've hit a pace or recovery ceiling you can't break through.
