The Glycogen Bottleneck: Why Your Training History Dictates Your Fueling (and Your Speed)

"Why the ‘Norwegian Method’ might be failing you." We are told that to go fast, we must first go slow. But for many junior or power-based athletes, "Zone 2" training leads to a frustrating plateau rather than peak fitness.

Discover why your muscle fiber architecture might be turning your "easy" miles into a metabolic drain that kills your top-end speed, and learn how to build the oxidative machinery you actually need to break through.
