Trail Runner Nation

Runners have more data, technology, nutrition products, and training advice than ever, so why does Dr. Phil Maffetonebelieve many of us are actually getting slower and less healthy? In this wide-ranging conversation, Phil challenges the resurgence of high-carbohydrate fueling, explains why building a strong aerobic system still matters, and shares how he used heart-rate training decades before it became mainstream. He breaks down the Maffetone Method, why runners should measure training by time rather than miles, and how slowing down today can ultimately help you run faster tomorrow. The conversation also explores the difference between collecting data and actually using it intelligently, along with Phil’s belief that diet and metabolic health can quietly undermine even the best training plan. And in classic Phil fashion, the discussion eventually wanders into music, creativity, awareness, and why becoming a better runner may require developing more of yourself than just your legs.
