When you run a marathon, you will burn a lot of energy in 26.2 miles. Because nutritional and energy needs are high, runners should strive for a balanced, nutritious diet to improve performance and endurance.
Calories burned while running a marathon will depend on several factors. Male runners, for example, typically require more energy for physical exertion than their female counterparts. Age is also an essential factor – older runners usually have a slower resting metabolic rate. Finally, body weight plays a role in calorie burning. For example, as a runner, you will burn more calories if you are 210 pounds than if you weigh 125 pounds.
Calculated calories burned
According to the Cleveland Clinic Center for Consumer Health, a runner weighing 130 lb will burn 2224 calories during a marathon, a 165 lb. A runner will burn 2822 calories and 210 lb, and the runner will burn 3593 calories.
While exercise is an essential aspect of marathon running, nutrition is also a key factor. You should have an adequate balance between energy intake and output and strive for balance and variety in the food you eat. A typical marathon diet contains 65 percent carbohydrate, 25 percent protein, and 10 percent fat.
