The article was great. I think it will make an interesting read for subscribers to The New Yorker, even those who have little or no interest in athletic pursuits.
The fact is that most of the regular population can't grasp what would motivate a person to run 26.2 miles.
What Kip did that was so interesting was that he seemingly put in just as much money, time, and effort into NOT running 26.2 miles. Moreover, he was/is a legitimate runner who posted credible times under 3:30. He wasn't cheating for the glory of crossing the line first like Rosie Ruiz. He was cutting a couple minutes from his modest PR. It's like breaking into a bank to steal rolls of nickels.
I was happy that Singer succeeded in getting an interview with Litton. He couldn't pry all the secrets from the man, but I'm not sure anyone will. Such is the nature of this very particular madness.
