The video shows a group of people participating in a marathon or race on a city street. The runners are of various ages and ethnicities and are wearing athletic clothing. Many people are on a green running path separated from the street. In the midst of the runners, a person in a wheelchair is being pushed along by two runners. Spectators line the sides of the road, cheering and taking photos. A large banner with the word "Barcelona" on it is visible, and there are several sponsor logos along the course. The environment appears to be a sunny day in an urban setting, with buildings and trees in the background.
