Decolonise colons!
It doesn't work the other way round, clearly.
Everyone race and see who's fastest means no women doing well in any top race ever. Hence the need for women-only competitions and the need for some set of rules to decide who qualifies for those races.
I honestly don't much care. Have men only races, men with women who want to be there races, women only races, whatever.
Trying to make elite/professional sports make sense or be "fair" is a fools' errand imo.
The list of rules just gets longer and longer and more intricate and the main beneficiaries are armies of bureaucrats and the shareholders of private testing labs.
