Not at all. This is a good proxy for the activities of wealthy people who don't care about privacy. I'd be interested in this map if I wanted to know where to put up ads for overpriced energy bars. But this isn't a map of physical activity.
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.
