The legendary "marathon monks" run a thousand marathons in a thousand days to reach spiritual enlightenment. Yet so much of Japan's running culture remains a mystery to the outside world, on par with many of the unique aspects of contemporary Japan.

Why does it make sense to Ethiopian runners to get up at three a.m. to run up and down a hill? Who would choose to train on almost impossibly steep and rocky terrain, in hyena territory? And how come Ethiopian men hold six of the top 10 fastest marathon times ever?

Despite believing he was bionic as a child, Ira Rainey was far from an elite athlete with superhuman running abilities like the ones he read about in books. He was in fact an overweight and unfit slacker who felt a bit sorry for himself because he had sore feet. Sure he ran a bit, but he also sat around a lot and ate and drank too much. Why? Because he could, and because he was a delusional optimist who thought everything would always be just fine.
