Strava is a popular app for tracking your runs and rides. Heatmap of bicycle use But the accumulated data that can be explored through the Strava Labs Global Heatmap is amazing! It is fun to look around and explore my area’s use for rides and runs. (But, I could have told you that 4th St. was bike highway for people leaving town.)

Looks like Strava, is now selling accumulated data to cities to help plan better bike routes. Portland is in.
