Didn't like it. For me it was too pretentious and the examples he used missed the point too often. But there are some good quotes, better to just break it down in one page and call it Ten quotes on simplicty.
A good read. What he's talking when he's talking about running is of course his life and the decisions he has made. Which really makes it into a memoir but centered around an important activity of Murakamis life, running.
