Another participant runs the 100 meters; after being eliminated in the quarterfinals, he catches her changing out of her race gear and into something more revealing... A third athlete takes part in the 100-meter hurdles; following her defeat in the semifinals, he follows her into a bathroom stall where they engage in rough intercourse before returning to the locker room for even more intense action... Finally, there's a fourth contestant who advances to the finals of the 200 meters. Our protagonist witnesses her pre-race stretching exercises that showcase her well-developed buttocks muscles.
