The image shows a large group of people running in a marathon. The runners are of different ages and genders, and they are all wearing blue t-shirts with numbers on them. They are all running on a road with trees and buildings in the background. The sky is blue and the weather appears to be sunny and warm. There are a few people standing on the side of the road, watching the runners. The image appears to have been taken during the day, as there are no other runners visible in the frame.
