The author’s argument isn’t that women are faster but that they can sustain physical exertion for longer. I have no idea if that’s true, but citing marathon times really misses the point.
If men can keep up a faster pace for over 100 kms, then they can sustain exertion for more than long enough.
The paper someone else posted showed that women start to lose pace in a marathon later than men, but men start out so much faster, and over the course of an ultra-marathon men still keep up a faster pace the whole distance.
Worth pointing out that there is lots of existing races that would compare “sustain exertion for longer”.
One called “backyard ultra”. Basically you do a lap of 6.7km each hour until everyone else drops out. World records are all men by a long shot - https://backyardultra.com/world-rankings/
Fastpacking, a slower event than the backyard ultras, involve hiking/jogging through hiking trails while carrying what you need. Definitely slower pace, and I’d argue closer to what I’d imagine with a long, days-long hunt would be like for ancient tribes. FKT, or fastest known times, are often found at this website. Looking at all the times, men carry a significant lead in both supported (ie someone else carries your food/water/sleeping gear), and unsupported. As an example, look at the Appalachian Trail – https://fastestknowntime.com/route/appalachian-trail
EDIT: The thing the article failed to mention (and the thing I think is key) is that women excel at doing these things, typically, with less energy burnt both during and after the races. Women on the whole are smaller, and tend to have better insulin responses (as mentioned in the article) which means their blood sugar stays consistent during exercise and after. Consistent blood sugar means less wasted energy. Larger heart and lungs, combined with higher type 2 muscle fibres compared to women’s type 1 means, again, less wasted energy and more efficiencies. Less muscle damage, as mentioned in the diagram, means less to repair, which means more saved energy. In a hunter/gather society, this saved energy can be significant.
With modern access to food, that evolutionary advantage seems to vanish, and the article doesn’t even touch on it.
