If that were true women would be posting the same or faster times as men in ultra-marathon races. Did you know that women who run regularly stop menstruating as a natural adaptation to the extra endurance requirements? You really should stop reading feminist propaganda.
Brain power doesn't seem to be your strength. Men run faster because they are stronger and have longer legs. Duh. Women have better endurance than men. It is a medical fact. Look it up.
From Livestrong.com
Muscular endurance is the ability of a muscle group to contract over long periods of time. Men have more muscle mass than women, but they do not necessarily have more muscular endurance. Although there is controversy as to how and to what extent muscular endurance differs between men and women, men and women consistently have similar levels of muscular endurance or women have more. Hormones, training, genetics and other variables may influence muscular endurance between genders.
That is just one place where you can find this info. Has nothing to do with what you call 'feminist propaganda.' Idiot. I used to be a long distance runner and usually my running partners were men, so don't try to tell me anything about it.
Here's another source, and if you actually bother to read it, or maybe you can get your wife or girlfriend to read it to you if you're tired out, you will find that women are known to have better endurance than men. You poor wimpy thing you.
