NOP has not been messing around so far.
That's for sure. I'm not sure why the rest of the world just jokes around indoors.
Yesterday, I asked Centro if Rupp gives him a hard time since Rupp's indoor mile pb is faster than Centro's. Centro said not anymore since I broke that time outdoors. He said somethign along the lines of, "We don't count indoor pbs."
It's clear that the NOP guys realize with no wind you can basically run as fast indoors as outdoors.
I think that part of the interview was recorded. You can listen here:https://www.youtube.com/watch?v=sx2vnD0FTEA
