Are you sabotaging your endurance performance by consuming too many carbs? In this episode, we break down a groundbreaking study on endurance fueling that challenges conventional wisdom. Does fat adaptation work for long races? How little carbohydrate is actually needed to perform at your best? Hosts Paul Warloski, Marjaana Rakai, and Dr. Paul Laursen discuss the science of fat oxidation, hypoglycemia prevention, and how endurance athletes can optimize their fueling strategies. Plus, Marjaana shares her experiences from Ironman races and a fascinating Scandinavian fueling trick involving coffee and Coke!

• Fat oxidation is crucial for endurance performance, but many athletes rely too much on carbs.
• A new study suggests as little as 10 grams of carbs per hour can eliminate hypoglycemia and enhance performance, regardless of diet.
• Muscle glycogen may not be as critical as once thought—maintaining stable blood sugar levels might be the key to endurance success.
• Fat-adapted athletes can still benefit from small amounts of carbs without losing their adaptation.
• High-carb fueling (100+ grams per hour) may not be necessary for all endurance athletes, but it could help elite competitors.
• Endurance nutrition should be personalized based on gut tolerance, training, and performance goals.
• Old-school advice (like pre-race pasta parties) may not be essential—fat-adapted athletes can perform well with a balanced, lower-carb pre-race meal.
