Partially agree there, without exposure a product does not sell - simple.
Look at the example quoted, the Olympics, and the audience settled to watch GB competitors in many sports, regardless of gender. The Olympic RR for men disappointed many, but the women's race in nasty conitions was a classic. At Putney bridge, where I was standing in the wet, the crowd was still there when the camion balai canme through with a little group about 20 minutes down, still cheering them - great.
That said, the Olympics were a "special effect" in that people did watch an awful lot of sport, so it's hard to get a true measure of whether a major women's race would get the audience. Mind, if most races were as brutal and fierce as the Olymopic one, the word would soon go around, the the audience numbers would start showing, and in would come the sponsors and organisers.
The idea of compelling teams to have men and women sections has an interesting issue - looking at BC site's annual report I think women are about 15-16% of the members, and about 40% have a race licence.
So, there may be a problem actually finding riders of a sufficient quality to justify any domestic sponsor paying wages - the last thing women's racing needs is a situation where a few class riders dominate and the rest simply trail in via small groups, that is not the spectacle that is needed. Which domestically can be the problem, either that or a very negative and steady paced ecvent with a sprint finish.
Resal may have a view on the last point, I am not convinced that simply compelling sponsors and organisers will have the effect expected, rather it might discourage them from investing in the first place, which helps nobody of either gender, or the sport in general.
