STRAVA Labs Heatmap is Cool

STRAVA Labs has created a global heatmap using data from users' bike and running routes. Pretty rad. The global map shows some pretty interesting things. It's no surprise that Europe has a much greater concentration of cycling routes. I didn't know Sao Paulo was such a hotbed of cycling activity. And how about Puerto Rico being lit up? It's also a little striking to see all of the active cycling routes in Japan and South Korea set against the nothingness of North Korea, though there's no surprise there. Of course I had to include a zoomed in view of Springfield, MO - shown in the bottom image.
