A visualization of Nike+ running data confirms runners are some of the most hardcore metropolitan residents. For example, in New York, some athletes run from borough to borough, several circles around Central Park or the entire span of the West Side Highway.
Nike+ City Runs is a software system that plops Nike+ running data onto a screen. Thick white lines bring thousands of runs to life. In the animations, viewers can follow moving dots, representing runners, along a map of each city.
