I have no experience to share (except that I have observed it's true that female racers tend to be quite muscular and not stick-people like many of the male racers I know).

But I did want to say "welcome to TE", "thank you" for the good thread you started (partly because I'm sure there are other people who read this forum who may not post but who will appreciate the discussion), and "looking forward to reading more from you." This is indeed a pretty special place on the internet.
