In Part 4 of the Masterclass, the focus shifts from physical training to race-week execution, logistical discipline, and mental strategy. The session outlines a proper 36-to-48-hour carbohydrate loading protocol targeting low-fiber, simple carbs to maximize glycogen stores without digestive bulk. It builds a reverse-engineered race morning countdown from pre-race meals to corral logistics, details early-race pacing mechanics to prevent the trap of "banking time," and equips runners with cognitive tools—like chunking, process cues, and reframing—to push through central nervous system fatigue when hitting the wall in the final miles.
