I want to preface this with saying I am fully supportive of LGBTQ+ rights and I believe that people can be born one way but their brain is wired for another.

That being said, if a large majority of your biological self was a man while you were growing up even though a lot of your brain was the opposite, then you will likely have a significant advantage (athletically) over those that grew up biologically as a woman.

This is in the early days of normalcy in society for trans people, so I think eventually this will work out. Perhaps racing events need something like a "weight" class like you find in some martial arts.
