Fast forward more than 10 years later, and the researchers checked in on the death rates of the people involved. People who identified as joggers were split into three main groups: light joggers, moderate joggers and “strenuous joggers” based on the information regarding frequency, how many miles and pace they provided at the beginning of the study. The results? Duh—joggers had a longer lifespan or life expectancy than non-joggers.

But wait, what about the sub-groups? The light joggers had the lowest rate of death, followed by the moderate joggers. And newsflash (sorry speedsters)–the strenuous ones tied with the non-joggers with highest mortality. What’s even more shocking? Their life expectancy, statistically speaking, matched that of a sedentary person. What?!
In short, the ideal sweet spot for jogging and gaining full benefit was 2 to 3 times per week. The optimal speed was slow, and the optimal weekly distance? 1 to 2.4 miles!
Take what you want from this study, but we found it interesting and somewhat surprising! Although we are all pretty confident we will continue to train for marathons, but perhaps a more leisurely pace. Because, if you run slow, who cares?
