For those of you who think bike racing has to be all or nothing I would encourage you to check out a mountain bike or cyclocross race. Road racing is pretty intense but I have found the vibe at mtb and cx races to be MUCH more social and laid back. I actually think bike racing can be MORE social than triathlon since you race so much - its really fun to see the same group of women EVERY weekend during the fall at cross races. You still have to be really committed to do well but there are definitely some ladies (especially at mtb races, less so with cross) (at least where I live) who just love to ride their bikes and like the social/fun aspect of the race scene.
