The video shows an aerial view of a marathon taking place in an urban environment. Many runners, a mix of adults, are visible, moving along a city street. On the left side of the frame are green trees lining the course. Overhead, there's an elevated railway track. A red train is moving along this track. Buildings surround the area. Traffic cones and road markings indicate a 20 mile per hour speed limit. Spectators line the sidelines of the marathon route.
