These benefits are realized further when walking or running with the treadmill on an incline. According to a study from A.T. Still University, walking on a treadmill at an incline of 10 percent or more will improve the muscles' benefits for a more intense workout.
Let's consider what types of food a runner needs before a long run, many of which could already be common staples in your diet. The most important things for runners to consider are carbohydrates, protein and fat. And getting the right balance of these three is important.

Before long runs. A few hours before any long run, eat a meal high in low GI carbohydrates, moderate in protein and low in fat to give your body all the nutrients it needs for the next few hours. Porridge with fruits, a chicken sandwich and fruit or a bagel and peanut butter are good options. During long runs.
