On his own Twitter thread he's written, I know less about this than trans people, so yes, I've listened to them a little bit.

No mention of talking to women.
This guy's had a almost a week to put this piece together. He 's chief sportswriter so presumably he knows where to get hold of Navratilova or Paula Radcliffe or Kelly Holmes. Or if no sportswomen wanted to go on the record, he could have asked why that might be.
Such a lazy, uninformed, unresearched piece of writing. How he has the nerve to identify as a journalist, never mind a chief sportswriter, is beyond me.
