A crowd of runners, many of them bare-chested men and women, are seen sprinting towards the camera in an indoor venue, likely at the start of a race. A burst of white smoke rises into the air as they begin. Spectators on either side hold up their phones to record the event. Behind the runners is a large screen, and banners along the sides indicate that the event is a "HYROX" competition in "PUEBLA." The venue features a high ceiling with visible structural elements.
