women and men should not be competing against each other in any event
the vast majority of the open or mixed sex sport categories are events that have been deliberately engineered to favour the physiology of men
for example, if an open sea swimming race event is long distance as in 20 miles or over, the majority of women will have faster times than the majority of men.
but how long are open sea swimming races usually? 10k which is only 6 miles!! (And that’s the Olympics length)
It’s not that we are always weaker and men are stronger or faster, it is that the majority of events are designed by men and for men to match their strengths
only by all sports being kept separated can we design women’s events to match our strengths instead of forcing elite women athletes into open/mixed sex categories where the events are literally rigged to favour men.
so yes all athletes should be tested so that men and women are kept separate in sports. It’s the only way to get more female world record holders and more girls to take up sports- to achieve gender parity in sports.
