The image shows a group of people participating in an outdoor event, likely a charity or community event. They are standing in front of a tall building, which appears to be a modern structure with a glass facade and some greenery on its roof. The participants are wearing green shirts with a logo that includes a stylized "3" and the text "Carnaval Madrid." They seem to be engaged in an activity, possibly a race or a walk, as they are holding hands and moving together. The atmosphere suggests a lively and energetic environment.
