Misconceptions About Carbohydrate Requirements for Running a Sub 2-Hour Marathon

Contrary to common belief, a recent study suggesting that runners need 90 to 120 grams of carbohydrates per hour to run a sub 2-hour marathon was scrutinized. The model implied that carbohydrates alone were necessary for this feat, debunking the theory. It was found that the assumptions made in the study, particularly regarding fat burning during exercise and the immediate utilization of ingested carbohydrates, were flawed. The study actually proved that running a sub 2-hour marathon solely on carbohydrates is not feasible.
