The image shows a large group of people running in a marathon. They are all wearing matching blue t-shirts with white designs on them. The people are running on a street with buildings and cars in the background. The sky is blue and the weather appears to be sunny and warm. The runners are closely packed together, with some people in the front and others behind them. They appear to be in motion, with their arms and legs pumping as they run. The overall mood of the image is energetic and determined.
