An easy to read chronicle of London Marathon as well as Marathon itself in the modern age. It contains many funny and useful anecdotes of people who have been participated in various form in this sport. Some of them are crazy and even criminal, yet they are united in their obsession in a sport that seems to exist only as a touting challenging to human's endurance of pain and suffering. I don't think that Marathon is a "fitness" exercise, but a form of activities that provokes our innate sense of conquering obstacles. It is a public and private venue for confronting our limitations thus stimulating our sense of defiance.
The style of the writing is factual with particular eyes for funny and unusual details. In addition, it does contain useful technical discussions about shoes, postures, injuries and preventions. For people who have eyes for a marathon sometime at least once in their lifetime (such is me), this book can serve as a reminder, a gentle goading voice whispering for us to join "the magnificent obsession".
