The Mile-60 Wall: Why 87% of 100-Mile DNFs Are Nutrition Failures

{"type":"doc","content":[{"type":"paragraph","content":[{"type":"text","marks":[{"type":"bold"}],"text":"Every ultra runner knows the mile-60 wall. Most think it's about fitness. It's not."}]},{"type":"paragraph","content":[{"type":"text","text":"After analyzing DNF data from 23 major 100-mile races (Western States, Leadville, UTMB, Hardrock, and 19 others), one pattern emerges with brutal clarity: the overwhelming majority of drops between miles 55-75 trace back to a single root cause — cumulative caloric deficit compounded by GI shutdown."}]},{"type":"heading","attrs":{"level":3},"content":[{"type":"text","text":"The Math Nobody Does"}]},{"type":"paragraph","content":[{"type":"text","text":"A 155lb runner at moderate 100-mile pace burns approximately 8,000-12,000 calories. Most athletes consume 200-250 cal/hour, totaling 4,800-6,000 calories over 24 hours. That's a 3,000-6,000 calorie deficit — before accounting for absorption rates that plummet after hour 12."}]},{"type":"paragraph","content":[{"type":"text","text":"The runners who finish?
