I just finished this book, and I have to say it was a good read. I have read Dean’s first book,Ultramarathon Man – Confessions of an all night runner, which I will review later, and both books are entertaining. 50/50 centers around Dean’s attempt to run 50 marathons in 50 days in 50 states. To make it clear, this is not a guy writing about getting up in the morning and pumping out 26.2 miles every day on the streets of his neighborhood. These are official marathons all run consecutively across the country! He calls it the Endurance 50, and it was his effort to raise awareness about childhood obesity levels rising in America. He recalls some of the tales from his first book in this one, but the stories all have a different twist to them so it is refreshing instead of redundant. This trip was also chronicled on film and made into a documentary using the same 50/50 title and again it is not redundant, they actually compliment each other and I recommend that if you do one you do the other. Although it’s filled with information this is not just a how to book, this is a story about a great undertaking and an incredible achievement. Each of the 50 marathons is remembered through his tales of meeting people and experiencing what each individual race brought with it. Sprinkled throughout the chapters are helpful running tips both from Dean and other top level runners and coaches as well as studies done on all things running. Overall, this book is a great read for runners of any level as well as non runners who might want to start. It is well paced and will make you want to keep reading as you marvel at this one man attempting to conquer the childhood obesity problem as well as each of the 50 states, one day and 26.2 miles at a time.
