We're from San Diego and Tucson.  Our friendship goes back to our college days in Boulder.  Now we do races together so we have more opportunities to hang out.  We all dabble in running, biking, triathlons and other endurance events, just for fun and sometimes for motivation to train harder.  We all did the Old Pueblo 24 and had a blast riding at night.  This should be even more fun, and it would be a bonus to beat some of the pro/sponsored teams.
