For this study, we analyzed 19.6 results from over 16 thousand marathon races. We recently published our mega-study on the state of running, where we found that the world, and in particular, the marathoners from the US are getting slower. We became curious to see how the 50 individual states +D.C. are performing.   Feel free to use any material from this page, as long as you refer to this original source.     We've also created a tool that can[…]

The number of obese children may rise to 70 million by 2025. That’s more than double the 32 million figure recorded in 1990. It’s not just about weight. Obesity is linked to major health problems like diabetes, heart and joint problems, disability, and even some cancers. The World Health Organization recommends at least 60 minutes or more of physical activity for school going kids but only 21% of 6 to 19 years old get to the bare minimum mark. Rather, a Kai[…]

We’ve analyzed 19.6 million marathon results from over 30,000 marathons. In our new study, we concluded that the world is getting slower.

The most obvious thing people do when they want to lose weight is some form of cardio. Instead of following the guidance of the misinformed, I conduct[…]
