There are quite a few women who race locally so they join us on Club rides etc from time to time. I trained with one of the Women's World Tour Pro's earlier this year, immensely strong and it was a privilege to see her in full flight up our steepest climbs - dropped me comfortably.
I don't care for random strangers to draft on my wheel or join me uninvited regardless of gender so don't do it to others which means any women I ride with is either pre-arranged or I know them. When I'm training I'm not socialising, anyone tries to get on my wheel gets dropped. Greeting one another when passing is normal here though.
