"Biological boy" is a nonsense phrase. Gender is a social construct, not a biological thing.
Yes hormone levels can be measured, but so what? Gender is a social construct. What does measuring hormones have to do with it?
Great. If that's the case, have ' they' run in the "social construct called boys", since it doesn't matter, and biology doesn't have a part.
Flies in the face of century of data showing cis males being stronger and faster than cis females, but if you say it's just a social construct, sweet. Curious how the social construct will sort procreating. I mean, if it's just a social construct, and not a biological one, then two trans women should be able to decide to be male and female, and have kids, right?
Also, while we're at it, let's allow taking testosterone supplements and other PEDs for cis males and females.
Were this my girl coming in 3rd, or 9th, and not making finals given cis males took 1 and 2 and she missed a cut because CT didn't test for testosterone levels, I'd sue the state athletic board. I'd ask for the two trans children to have their wins set aside, and for my girl to be given first. If there was a race following this, I'd ask for an injunction to prevent the trans kids from running.
Last, this op Ed piece said it well. She's allowed by law to compete as a girl. Was it fair ? No.
