Running a marathon burns thousands of calories, with some estimates suggesting over 2,600 calories are expended during the race itself. Therefore, understanding how many calories to eat while training for a marathon is crucial for fueling your body and achieving your best performance.

Studies have shown that inadequate fueling is a primary cause of fatigue and poor performance in endurance athletes. So, to optimize your energy and recovery, you need a precise strategy for how many calories should I eat on a long run day.

Studies show endurance athletes have significantly higher energy needs, sometimes requiring over 4,500 calories daily. So, should I eat more when training for a marathon? The short answer is yes, and understanding the 'why' and 'what' is crucial for a successful race.

Endurance runners can require over 4,500 calories per day during heavy training, far exceeding the needs of the average person. To sustain performance and promote recovery, a runner's diet must be carefully tailored, so understanding **how much should I eat as a runner?** is critical.
