Who coaches Usain Bolt?

Who coaches Usain Bolt? Any idea of how he is being trained?

His scholastic coach, Dwight Barnett.

any idea what type of program he follows and or what kind of work he does?
This boy has been in top form since indoor.

I was informed by a colleague in Jamaica that he gets a “good diet” of speed endurance work. Not known are the durations, volume or intensities.

Interesting discussion concerning his present perspective and, quite possibly, future aspirations on IAAF and T&FN boards.
