You might want to check the Bay Area Velo Girls website for some ideas. They have a lot of clinics for women, from basic skills up to racing clinics.

I think the trick is to make it accessible and non-threatening. When I started road biking I was so indimidated walking into a bike shop - I was afraid someone would walk up to me and say, 'hey chunky middle-aged woman, what'r YOU doing here?' I don't quite remember when I started to feel like I 'belonged', it must have been after I bought my road bike and had been riding for some time. The other big help was joining an all-woman training ride series which prepared us in 10 weeks' time for a metric century (again, all women) - it was a great environment for me to learn the basics and get comfortable with road riding.

anyhow, just some random thoughts, - Jo.
