The book is written by a runner named "Dean Karnazes." This man has proven how extraordinarily a person can perform in their life. Just imagine, running 560 kilometers continuously for 80 hours without sleep or stopping... that's the distance from Mumbai to Goa! What's particularly interesting is how the human body changes during such a run, how the mental state shifts as the distance increases, the pain, and the remedies... his experiences make you think about many such minute details. He beautifully illustrates, through his experiences, how a sportsman, his work, his family, friends, and his sport all tie together. Although he ran alone, he always stayed connected and won with his family, friends, and many colleagues as a team.
