In my opinion, the best training book out there is The Cyclist's Training Bible by Joe Friel. The difference between it and most others is that it contains more on training technique and scheduling, rather than workout technique and routines. There is a lot of good workout information, too. And, it looks like VeloGear has it for a steal, right now. Almost any bike shop with a book section, or large bookstore will probably have it, if you want to thumb through one.

I emphasize training "technique and scheduling" above because any work-out regime has the capability of producing results if carried out correctly, or failing to produce results if not.
