Thank you.No, sorry, should have been more specific. It's closed to those born female who still identify as such. Here's a link to the actual policy:
The categories for swimming are:
- Female – athletes with a birth sex of female
- Open – athletes with a birth sex of male, trans or non-binary competitors and any competitor not eligible for the female category
( The updated policy ensures there are entry-level competitive opportunities for transgender people to participate in the majority of our disciplines within their gender identity).
The reason I'd feel that it's called "open" then, is that it is involving multiple "groups" of people, and it's likely much easier(?) for a sporting body to call sporting categories Men/Women/Open than Men/Women/Trans even if the open category isn't truly "open" in the sense that literally anyone can enter the event.
