There's a whole lot of "might" and "maybe" being thrown around here. Honestly, I think the biggest factor in these longer distances is the smaller sample size. There just aren't as many elite athletes competing at the ultra distances as there are at marathon and shorter distances.
The article throws in a bit of speculation about how men might be socialized to run too hard at the beginning of a race. I disagree. That observation says, to me, that the men competing in these events are not as well trained, not as experienced.
Look at the men's marathon and you'll see everyone taking it easy at the beginning of the race! They have to hire people to push the pace in the beginning because the elite runners don't want to do it. That directly contradicts the speculation about male socialization.
