Back to Sara. I think Ex has encouraged you to focus on age group racing when it comes to results. I concur with this advice. Do the other races for training without any great concern on outcome. Finishing is fine. I know that can get expensive, so maybe a local weekly training race would work. It would get you experience and fitness. Then focus on the Senior Games, Nationals, state championships, stuff like that for results. There has to be enough of those events to build a set of "A" races for a season.
Somehow, though, I think you are going to end up on the track. I bet there's a nice group of 60+ women in your area that ride track.
