Moderate running has been shown to have many benefits for heart health, including reducing the risk of heart disease, high blood pressure, and stroke. This is because it helps to improve cardiovascular fitness, lower cholesterol levels, and reduce stress on the heart.
On the other hand, marathon running, and intense endurance exercise in general, can be detrimental for the heart. Some studies have suggested that intense endurance exercise, such as marathon running, may cause inflammation and damage to the heart muscle, which could increase the risk of heart disease. Additionally, intense endurance exercise may also cause an abnormal heart rhythm called atrial fibrillation, which can increase the risk of stroke.


Moderate running, such as jogging or running at a steady pace for 30 minutes to an hour several times a week, has been shown to have many benefits for heart health, such as increasing cardiovascular fitness, improving circulation, and reducing the risk of heart disease. However, running a marathon or other long-distance race can put a lot of stress on the heart, particularly for those who are not used to intense exercise. This can increase the risk of heart problems, such as arrhythmias, heart attack, and sudden cardiac death. It's always important to consult with a doctor before starting any new exercise program, especially if you have any underlying health conditions or risk factors for heart disease.
