Do Cyclists Really Need 120g of Carbs Per Hour?

Do cyclists really need 120 grams of carbohydrates per hour to perform at their best—or are amateur riders copying a Tour de France fueling strategy that was never designed for them? Ultra-high carbohydrate fueling has become one of the biggest trends in cycling nutrition. Professional cyclists are reported to consume 90, 120, and sometimes even more grams of carbohydrates per hour during the hardest races. But that does not necessarily mean every cyclist should follow the same fueling plan. In this video, Trevor Connor and Chris Case examine the science behind consuming 120g of carbs per hour while cycling. They explain carbohydrate absorption, gut training, glycogen sparing, gastrointestinal distress, and why the nutritional demands of a three-week Grand Tour are dramatically different from those of a weekend race, gran fondo, group ride, or normal training session. You’ll learn what “ultra-high carbohydrate” fueling means, why Tour de France riders consume so much food during a stage, whether higher carbohydrate intake always improves performance, and why your ability to absorb and use carbohydrates may be highly individual. The key question is not simply, “How many carbohydrates can I consume?” It is, “How many carbohydrates can my body actually absorb and use without compromising my performance?” Have you tried consuming 90–120 grams of carbohydrates per hour? Did it improve your ride, or did it leave you feeling bloated and uncomfortable? Share your experience in the comments.
