The image shows a large group of people running in a marathon on a city street. The street is lined with tall buildings on both sides and there are trees and lampposts on the right side of the road. The runners are of different ages, genders, and ethnicities, and they are all wearing running gear and running shoes. The sky is blue and the sun is setting, casting a warm glow over the scene. There are a few people standing on the sidewalk, watching the runners. The overall mood of the image is energetic and determined.
