They're not really addressing the issue though are they ? All they are doing is effectively banning one particular athlete from their prefered events by saying her testosterone levels are too high for these distances.
It's just muddying the waters even more. Is the eligibility for those distances now not based on binary gender but on T levels ? Will female athletes with low T now boost themselves to the accepted limit ? If I get my T levels low enough can I give the 800m a bash ?
Semenya was born and raised a woman. A woman with higher testosterone levels than usual. This gives her an advantage, we don't know how much of an advantage though. The world of sport is full of competitors who have been blessed with genetic endowments(no jokes please) and huge physical advantages that are unfair.
I get the concerns about trans athletes, I really do. There certainly needs to be a discussion around that issue. But I'm not buying into the trans panic stuff that has burly 18 stone guys calling themselves Julie and sweeping up all the records and medals from the 100m to the synchronised swimming. The majority of that stuff is just bigotry. There's a solution and a compromise there, it's just going to take time.
Incidentally, the Semenya case, which was ostensibly settled by her gender test 10 years ago, only really reared up again after her win in Rio and the tears and snotters from the 6th placed Sharpe and the racist Polish lassie. Perhaps one for the conspiracy theorists, but I'm pretty sure that Sharpe's dad is quite good pals with a guy named Seb Coe ...
