I would expect that the average pro woman, holding marketability and relative placing equal, still makes less than a comparable man in terms of sponsorship money. Women's sport is by far not as developed as the Men's side for just about every sport, triathlon included - I see no reason why sponsorship dollars not also follow this pattern even at the top.

Take a look at the share of 'blank space' / unsponsored area on the tri suit that men have on their jerseys vs women. It's not a perfect 1:1 relationship between pure dollars and available real estate left on the jersey, but I couldn't help but notice that even Ryf, who is a the surest bet in the sport, still has room to put a Swiss flag design on a prime real estate area on the tri suit. Compare that to any of the top men.

What makes you think that women earn more sponsorship money than the men?

N=1: I follow A LOT more women athletes on Instagram than men.

This is always a here we go argument. Triathlon as fair or unfair as it may be actually has pretty good equality in pay at the races. What the total sponsorship pkg is I don't pretend to know. Look at Tennis, golf, soccer, basketball and baseball/softball if you want to see some pretty big differences in payouts. There is a lot of argument as to the money the sport brings in in total revenues which does not apply to triathlon, but the reality of the matter is there is a huge discrepancy between mens and women payouts at the pointy end of the field in sports. I don't know where the transgender figures into the mix, but with recent topics it seems to get some attention.
I don't have a dog in that hunt, but if I was a woman and a huge sized transgender beat me in a sprint or strength event, I might. Lots of complications to the issues there, and I am not a part of the discussion.
I have more difficulty with the "Dr." issue with Rachael than the transgender. If you are in a clinical situation, MD or Doctor is acceptable and the norm, out on the street an MD is a regular person in my book. PhD the same thing, if you are in the educational venue Dr. is ok. When you are in the sports venue, you are just another cat in the game. I sort of laugh at people including their alphabet soup initials in their regular role in society, sort of the all hat no cows argument. Like who cares waiting in line at a dining experience how many letters you have behind your name? But then silly me, I still call Generals, Colonels, Senators, Mayors, Master Gunners and Chiefs by their earned titles. Oh, what the hell.
