Yes, obviously. But there's enough Strava users that that's a pretty good proxy.
I recently saw a small sign nailed to a tree on one of the thousands of back roads in the area that basically turn into a parking lot during rush hour.
I'm sure you would catch some flak for spamming on nature trails but normal streets are less offensive.
[edit] I guess the items highlighted in the blog post probably require some coin...
It is, but I suspect that runners still tend to be affluent. Just why is an interesting question.
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.
