Why not just have them compete against another trans athlete in their skill/race/sport? If there aren't any other trans to compete against, they compete against the clock. Thistle makes a good point in that, they're always talking about being able to do what a man does,...etc? What better time and situation to step up and show-TF-out for trans by facing a supposedly stronger competitor, a man, and beating him? Since they used to be a man, that's the best scouting report you could ever hope for on an opponent! It's really just an arbitrary cluster-fucking litmus test to see how much we'll tolerate.
