As a cis-gender female athlete (non-elite, but hey, I was an age-grouper for a long time) and a coach for girls' athletics, it's an interesting issue to have to try to work out. There has to be a way to ensure that all athletes are able to compete as the gender that they identify with, and yet ensure fairness for all athletes as well. It's such a difficult thing, and I am glad that there are smarter people than me working on it.
