There was a display at an airport I read about. Had a projector showing the average speed for a champion marathon runner. Most normal people couldn't match it over the short distance.
Couldn't find the link but here is a similar video of people (mostly amateur runners) trying to match a 2h marathon time for two minutes:
At ~160m, (similar to the 200m), at-pace speed for the pro is already all-out for the average person.
