Gender and pro cycling

[MightyMitre]

I live in Brighton, which is pretty much the unofficial gay capital of England. Each year we have a HUGE pride march in August which attracts thousands of people and it's fantastic. A lot of shops and restaurants round here sport the rainbow badge in their windows, there are a lot of gay clubs, the best being called Cruise (which is I think is a great name for a club.) Gay men and women are very open here, holding hands, kissing, doing the kind of things everyone does. I love living here - mainly for the fantastic diversity of people.

There was a case a few years ago in England about Time Trialling, where among other things the regulations specify you provide your gender as at birth, which would obviously be problematic for a TG competetor. I didn't follow the story right to the end, but basically the girl in question argued that although born male she was now female and should therefore compete against other women, not men.

My only questions about a transgender competetor just goes to show my ignorance on the subject.

Despite surgery wouldn't a TG rider still physiologically be male and therefore be stronger? For example, despite gender reassignment, a male heart and male lungs are probably larger than women's and could work harder/have greater capacity. I don't know enough about the process, but despite hormone treatment wouldn't a TG rider still have stronger muscles that could develop larger than women's?

In my current ignorant state, I could understand how, if a girl found herself on the startline with someone who was TG - they may be suspicious that the TG rider may have an unfair physical advantage because they still have male genes.

Would this really be the case?
