Running at conversation pace stimulates profound physiological adaptations. It increases capillary density, improves fat oxidation, and strengthens connective tissues without the accumulated fatigue of high-intensity efforts.
“Slow down to run faster.”
This counterintuitive advice is the cornerstone of almost all successful elite training programs. The bulk of your miles should be truly easy.
