An Insanely Detailed Map of Where People Bike and Run Around the World

Earlier this year, Nathan Yau visualized some of the world's most popular running routes, but with a fairly limited data set. But the information logged to Strava provides a wildly detailed map of people's workouts across the entire planet—and now you can explore it to your heart's content.

Indeed, the Strava dataset includes over 77 million rides and 19 million runs, represented by a staggering 220 billion data points. Pan, zoom, and be gobsmacked using their interactive map. To really drive home the point, we zoomed in and in on Manhattan. Check out the detail below—it's insane. [Strava via Flowing Data]
