The best way to show how good the elites are is to put a "lucky fan" from the crowd onto the track to run as well. It would be hilarious to see a semi-fit track fan trying to run the first lap of a 1500...
It is the same with boxing. If you really want to show the power of boxers, just allow fans to "try a round" with the pros. Televise that and you'd see very clearly that pro athletes are a different species.
