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.

Race Day. Susan Powell of Runners World recommends drinking 16 to 24 ounces of fluids -- either water or a mixture of water and sports drinks -- two to three hours before a half-marathon. This will give you enough time for your body to process the water, so you shouldn't need to go to the bathroom during the race. About 30 minutes before the race begins, consume another 5 to 7 ounces of liquid. This should be your last intake of water before the race.
