Query: It's all here in one little package.

I've been in search of the right Ironman training book for a while. Most regular tri books devote little time to IM training, and others are so complicated they're intimidating (The Triathlete's Training Bible has great information, but I find it really complex.) This gets it right. If you're a nerd like me who likes to understand the logic behind a training program, you can get it here. You can also skim for tips or workouts if you just want to know what to do and when. Especially great is the nutrition section -- Gordo has some very logical, no-hype tips that really work.
