Bernard Lagat's Coach

Here's an article in the NY Times about James Li, the coach of US runner, Bernard Lagat. I found this interesting about Lagat's training and Li's commentary on it:

Many distance runners train twice a day and run 125 or so miles a week. Lagat has maintained his health and sharpness by training once a day and running about 65 to 70 miles a week. “If I’ve been able to do one thing, it is to liberate myself from what is written in a book,” Li said.
