Congratulations! That is really a good feeling. If I lived near you I'd buy you a beer and give you that book "Younger Next Year." I just did my semi-hilly 15 mi. "time trial" in 17.4 and that's at least 1 mph better than I could do it last year. Now I'm thinking that next year (when I'm 64) I'll be knocking on the door of 18 mph. Rock on!
