In reply to Malcolm Tucker's Sweary Aunt:
Far from life imprisonment, he just gets his day ruined. It just so happens that the day he chose to risk ruining was one of the most important days of his sporting life.
When I watched it at the time even I thought he could be disqualified for doing that, and I'm not even a runner. He must have been much more aware he was pushing his luck, so either he wanted the publicity and/or he was stupid.
Edited to add second para.
