On: The World's Athletic Activity Mapped

>running is pretty much one of the cheapest sports/pastimes/activities one can do

It is, but I suspect that runners still tend to be affluent. Just why is an interesting question.

Interesting survey. Though I think the survey demographic is not representative of the general population.

Most people who run, or consider themselves runners or joggers don’t run 4.5 days per week and/or average 29.5 miles per week.

Interesting nonetheless thanks for sharing.
