NYC Marathon 2013 time-lapse

4K Ultra HD video: Runners passing through Brooklyn at the 10K checkpoint of the New York City Marathon on November 3, 2013. The participants are headed north on 4th Avenue along the western edge of Park Slope towards Downtown Brooklyn, and, because the D and R subway lines “run” underneath 4th Ave, there are even more people traveling this corridor than are visible!
