Remember, he said up to 15 laps in 20 minutes. Much of what PJ wrote seems quite similar to what we know of GPP for MVP, with the exception of the high volume part.

Steve Francis has said that he doesn’t have athletes running over 20 minutes because he believes it to be bad for sprinting. I take it that Bolt is actually running for however many laps he gets in within 20 minutes, not that he goes out to run 15 laps.
