@zrb Cos women are, on average, not as strong as men, they'd never win if most sports weren't segregated by gender. Even female runners like Caster Semenya aren't as fast as the best male high school sprinters.

That's certainly the post-facto excuse.
Historically though a lot of sports were segregated as soon as women started beating men.
This is the case with shotgun skeet shooting - a mixed Olympic event from introduction in 1968 until 1992. What happened in 1992? Zhang Shan, a Chinese woman, won gold. Women were barred from competing in 1996, and a separate women's division introduced (with different rules so there's no risk of women objectively beating men) in 2000.
