If you are still looking for rides in AZ, check out this site http://www.pbaa.com/Home.html

I grew up in Southern Arizona and visit home often. The site mentions a number of rides but I have only done El Tour de Tucson. It was a BLAST! Plus since it is in Nov., it usually isn't very hot. I highly recommend it. The site also has a map of the route, if you want to bike it during other times.
