Dean Karnazes ordered a pizza to a 200-mile relay while running alone through West Marin.

1. Nutritional Revolution Podcast talks with Dean Karnazes about ultra running nutrition, recovery, and endurance fueling. 2. Kyla Chanel interviews Dean Karnazes, a Greek American ultra runner and New York Times bestselling author, because his 30-plus years of racing give the episode practical weight. 3. The episode asks how Dean has stayed injury-free while racing about 30 times a year and how his fueling changed over three decades. 4. Dean retells the Western States 100 mile endurance run and the Badwater ultramarathon as early proof that he kept pushing farther than standard race distances. 5. He describes entering a 12-person, 200-mile relay alone from Calistoga to Santa Cruz and running through Petaluma and toward Nicasio. 6. During that relay, Dean says he ran out of food and used a flip phone and credit card to order a thin-crust pizza delivered on course. 7. He explains that he asked for the pizza unsliced so he could roll it up and keep running while he ate it. 8. Dean says he first treated nutrition as a simple math problem: "a calorie is a calorie." 9. He then tried carbo loading with pasta and pancakes, which led him to notice big peaks and horrible crashes. 10. He says that experience pushed him to distinguish between simple sugar, complex carbs, protein, and fat. 11. On the Spartathlon, a 153-mile race from Athens to Sparta, he tried to recreate ancient Greek fueling with figs, olives, pastilli, and dried figs. 12. Dean says that after about 24 hours on that fig-heavy approach, his digestive system reacted badly and taught him to watch fiber intake. 13. He says he now reduces fiber before races and leans toward rice cakes and other lower-fiber carbohydrate sources. 14. Dean says he has moved toward high-quality proteins and fats and away from many packaged foods in daily eating. 15. He cites Jack LaLanne's line, "If man makes it, don't eat it," as a rule that shaped his food choices. 16. For race day, he uses more manufactured products, including Hammer Nutrition's Perpetuum, plus nut butters, olives, and salty solid foods like souvlaki. 17. He says he aims for about 250 to 300 calories an hour, often using concentrated packets such as nut butter and capsule-style fuel. 18. Dean says cold-water immersion, compression, active recovery, and plain water help him recover, and he notes that he sometimes mixes sweet potato with tuna, olive oil, and olives because carbs now feel more sensitive. 19. The interview style is conversational and practical, with Kyla Chanel asking follow-up questions and Dean answering with stories from Greece, Marin, and long races. 20. People interested in ultra running, race fueling, and sex differences in endurance will get the most from it, while listeners wanting a short celebrity interview may skip it.
