Yes, to reduce expectations but also as a world class athlete racing a pack of world class athletes, he cannot dictate pace. If the pack doesn't want to run WR pace there is nothing Kipchoge can do about it. He cannot by himself in a competitive race go out and run WR pace from the gun. Doing so would be foolish. He could blow up and get caught by the pack. Don't forget these are professionals racing for money which gets paid out by the PLACE. He is racing the other guys. Time is secondary.
That didn't make any sense at all.
