Running Maps

Now this is cool. Flowing data has gathered a number of activity logs and mapped out the most popular routes of major metropolitan areas. These maps are from RunKeeper, so the routes from your humble Strava-using bloggers are't included, but it's still interesting to see. His conclusion:

If there's one quick (and expected) takeaway, it's that people like to run by the water and in parks, probably to get away from cars and the scenery. In the smaller inland cities, there seem to be a few high-traffic roads with less running elsewhere.

Of particular interest for us is the Boston and the Washington DC maps.
