Okay so I am not a runner, not even close, but I did think this book was motivating, interesting, and fun to read. The stories are all true stories from elite Olympians to casual joggers, who run great distances, average distances, or are just starting out. There is also a whole chapter on triathlons. Some of the stories include: Runners World's Mark Remy, U.S. National Team marathoner Josh Cox, Amputee Lindsay Nielsen, and a man declared brain dead! These stories really made me realize the dedication some people have and how it is important to do something, for these people it is running. I personally liked reading the stories for the new runners, since they are not to far from the point I am at right now. Overall, I would say this is a good book for anyone in sports since it is inspirational stories of "energy, endurance, and endorphins" all of which athletes face everyday. Whether you are a casual exerciser or sports player or professional, the stories are inspiring.
