A few hours after World Athletics announced it had banned transgender women from elite female events, someone tagged Parkrun UK in a tweet, and asked: “Will you follow @WorldAthletics lead and ban transgender women from women’s athletics at all levels?”
It was only one post by one person with a hundred-odd followers, but the tweet calling for transgender women to be barred from an organised run was seen by nearly 20,000 people in 24 hours.
