The image shows a group of people participating in a marathon. They are all wearing green costumes with numbers on them, indicating that they are participating in the race. The costumes appear to be made of fabric and have a shiny finish. The people are walking on a street with buildings and trees in the background. Some of them are holding up their hands in the air, as if they are cheering or celebrating. There is a large red balloon on the right side of the image. The sky is blue and the weather appears to be sunny and warm.
