I don’t know whether the soviet “women” who excelled in a few Olympic events in the 50’s were actually trans women or were simply men passing themselves off as women. The only true trans woman athlete I remember was a tennis player, American, who competed briefly several decades ago and did not become a star. In reality only superb physical specimens can compete at most levels now. The playing field is never level. I have a grandson who, at 16, is 6-6 and weighs 275. It was literally unfair to anyone who had to line up against him in middle school football. But that’s the way it is. I’m willing to wait and see what happens with trans athletes in the future; we may need to sort sports into weight categories or some such anyway.
