edit: Also, look at the graphs in the swim link. The trend lines clearly show there's a distance where the difference will reach 0% and guess what happens after!
The sentence you re quoting is from a site showing an across-the-board advantage for men, which gets smaller, but does not disappear, as distances increase. Literally every graph on the page shows that men are faster, in both swimming and running events, at all distances. But somehow you managed to read past all of that to find the one sentence that kinda-sorta says what you want to hear.
Impressive.

The study below suggest otherwise (for running, which I learned about in a different HN post, I'll defer on the swimming bit that I have no idea of or thoughts about)
"[...] women become faster than men at the most extreme distances over 195 miles long."[0]
