The video shows a large group of people running in a marathon. The runners are of various ages and ethnicities, and they are wearing athletic clothing. They are running on a paved road, and there are buildings and trees in the background. There is a large archway that marks the starting line of the marathon, with the logos of Fundació La Caixa and El Corte Inglés. The sky is clear and blue. The camera is handheld, and the video is slightly shaky. The sound includes music and the sounds of people running.
