Query: Quite Simply, It Works!!

I picked this book up the day I decided to run a marathon. I started with just getting out and walking. My aunt and I followed the book and worked our way successfully up to the Los Angeles Marathon. If you follow this book, you WILL SUCCEED. The simplicity and inspiration you find in this book makes it great for a beginner runner...especially if your goal is not of time, but just to finish.
