To be fair, you can't build a top end pro race calendar, and the associated salary/support structure, without a steady stream of top class riders coming through from grass roots/national racing. At this point, they don't do themselves any favours.
Doesn't matter what you try and do as far as organising races or coordinating/sponsoring teams, a lot of women just won't race.
I've sunk dozens (hundreds?) of hours, secured hundreds (thousands?) in sponsorship/expenses for womens racing over the 3 years i volunteered for the region, had 30 or 40 women ride once, decide its too hard and never bother again. Just a core of 3 or 4 who would race fairly regularly.
Have had a couple who have carried on and made it as internationals. The majority just stopped. So i did too.
You rarely get the ride once, then quit, on the blokes racing side of things. There are guys who i used to race with as a teenager (who were crap then) who are still racing now, 25 years later (and are still crap), paying their 15 quid week in week out to get a kicking from fitter and faster guys who are 30 years younger than them.
Oh, and FWIW, now i live in Sweden (one of the more gender equal nations in europe) we still have a mismatch between mens and womens racing. Mens races usually have 30-40 starters per class, women usually have around 10, makes the racing very dull, with only 10 riders, turns the race into a procession to the sprint finish, even in elite racing.
