The video shows a large group of people running indoors in a competition or race. They are running on a grey concrete floor marked with white lines. Some are wearing athletic clothing, including red shirts and black shorts. There are black curtains or backdrops along the side of the course with white lettering visible on at least one. A set of yellow obstacles are visible on the floor. The building appears to be a large indoor arena with a high ceiling. Hands holding a red object are visible in the foreground, suggesting a spectator's perspective.
