So what if you can run 1 second faster than some other human on a predefined course. You are still better than 99.99% of the rest of the humans.
Humanity is multi-valued, what your abilities are in one narrow (and ultimately useless) field should not in any way degrade the people lower in the 'ladder' and it should not reward those higher up.
Competition sports are historically good for two things only (and 'good' is up for debate), inspiring nationalism in people and paying exorbitant salaries to the competitors because of the media spectacle.
edit: Our capability to measure time is what drives this crazy competition forward, if we were limited to say 1 second intervals plenty of women and plenty of men would be able to compete just fine (only not in the same race, but for instance simply against the clock).
The differences between all humans competing in these races and the 'rest of us' is essentially so small as to be meaningless.
