People that consistently run even just 50 minutes per week have a 30% lower all-cause mortality and a 50% lower heart disease related mortality.

The question still remains whether there is an “optimal” running dose… and even if it does exist, it may vary from person to person. Other studies have found that even extremely high levels of running (40 miles per week) have been linked to a 26% lower risk of coronary heart disease when compared to someone that runs “only” 13 miles per week.
