For the IAU records on Wikipedia, yeah. A couple things to keep in mind, 80% of the people who complete an ultra marathon are male. And the gap between the sexes, some estimate around 4% for ultra marathons, seems to be trending down.

Here's better research I found. You're right, men still win more often and have the records. But honestly it's more complicated than just who is faster.

As I said to them above- it's like suggesting that Olympic target shooters would make the best range hunters. Just being able to run long distances quickly is not any sort of indication someone will be the best endurance hunter.
