The majority the the information in this book was very basic and common sense. I bought it while training for my my first triathlon but did not find it helpful. I attended a clinic put on by my local triathlon club and found that one hour investment worth more then this book. It could be cut down to three short chapters and still cover the basics(equipment considerations, training, and race day details.
