This is a good book to have if you know nothing about nutrition and want to learn some of the basics. You can collect all the basic information here through general Internet research. True, it's nice to have it all in one place in a logical format, but I really expected much more detailed advice for a book targeted specifically to endurance athletes than 'you need to manage your carbohydrates over the length of the event'-type advice. Not worth the money in my opinion.
