as for the men a re sprinters and women are long distance runners men dominate women by very large margins in both fields. The best female runner at marathons come muck closer then they do to the best male sprinters (would pure strength dominates) but men still win all of the major marathons. Men are simply more athletic then women are. I know there plenty of experts who spend considerable time effort blowing smoke up each others asses trying to prove that isn't true but that doesn't really change things. It possible that if the push long distance running far enough it boil down to will power and fat reserves and females might gain parity but that is simply finding an exception to the rule.

Not PC I know but reality isn't PC.
