Anyone have a godd basic book that they could reccomend for a cycling newbie. Something that addresses heart rate zones, interval training, and the many abbreviations I see here on the board. I'm 30 and have been cycling(or any aerobic activity for a few months now) but I definetly have the bug. WHile I know I'm not going to become a racer I would like to be able to train in the most efficent manner. Not too mention it would be more fun if I wasn't dropped so frequently at the local rides. Thanks for the help!
