This seems like a fairly bad example to compare with?

These runners do not even look like amateurs. Look how the best of the bunch still does the novice mistake of decelerating _before_ the finish line. They're just regular people asked for "let's try to run a 100m sprint". It doesn't take an Olympic champion to get a 3+ seconds lead in such competition.

The above-average track runner would look the same in this video. And the Olympic champion might have an 1s+ lead on them, which is still a lot, but not as lot as in this video (at least they will both fit in the camera).
