The image shows a large group of people running in a marathon. They are all wearing blue t-shirts with a logo on the front and black pants. The people are running on a street with buildings on either side. 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 of the group and others in the back. They appear to be of different ages and genders, and they are all focused on their race. The image seems to be taken during the day, as there are no other people visible in the background.
