I just read the RW interview with Rupp and must admit I have a lurking suspicion that he's gonna win on Sunday.
He was pretty close in Boston and I feel like the Chicago course is suited to him. He says in the story his top goal is winning, not the pace. He's NOT going up against Kipchoge. He IS pretty damned consistent in being in the mix. It's only a matter of time before he pops off a victory, a la Meb, as long as he is in the mix.
I think Sunday could be it.
