The point is that When Kipchoge speeks of PB instead of WR, it’s clear that he isn’t being honest at something, doing some sort of trickery strategy. No honest man would speek of running a PB in a marathon when it’s an 8 seconds margin from WR. In fact if he gets a PB and not a WR, that would be one of his greatest disappointments. So he is aiming for a disappointment? And to all those thickos who say “his PB is 2:00:25”, the only thing that this argument is implying is that he aims for sub 2:00:25, because he is speaking of PB. And according to you he’s PB is 2:00:25. Very dum argument
His PB is 2:00:25 and he's going for a PB. Very obvious, you idiot.
