Marathon & Half-Marathon Fueling: Gels, Chews, and Carrying It All

The wall at mile 18 is usually a fueling failure, not a fitness one. The rule of thumb: 30–60g of carbs per hour after the first hour, practiced on long runs until your stomach agrees. These are the products you'll see at every marathon start line in America.
