What happens here

This video captures a scene from what appears to be a marathon or a large running event. Numerous participants are seen running down a city street while spectators line the sidewalks, cheering them on. One spectator is holding a sign that reads 'SHOULD I CALL YOU AN UBER?', a common humorous message seen at such endurance events. The video does not depict any DIY project or instructional content.
