Mr. Bean participates in a running marathon across London where he starts a rivalry with another runner. While running, Bean and the runner cheat by riding a taxi and departing without paying the fare, thus causing the driver to chase them until the runner hits a post box, injuring him. Bean then continues to run, but he accidentally releases a dog, resulting in the dog chasing and biting him when reaching the finish line, resulting in Bean both winning the race and ending up in the hospital along with the runner.
