Kiplimo and defending champ John Korir hit full send on this one and went for it. They ran the fist 5k in 13:58 (1:57:52 pace). They hit halfway on world record pace (60:16) and the next few miles were even faster than that pace. By 30k (1:25:31 - 2:00:16 pace), Kiplimo was all alone. Still on WR pace at mile 22, he slowed a lot late however and had to settle for the #2 time in Chicago history. Tokyo 3rd placer Hawi Feysa of Ethiopia (2024 Frankfurt champ) had a big day as she lowered her pb from 2:17:00 to 2:14:56.  It was a tough day for the American women. Natosha Rogers was 6th in 2:23:28. *Full race broadcast

"I’m all in favor of the death penalty suspension from all competition if you test positive. One and done, that’s the way it should be. And then also these athletes aren’t operating in a vacuum. They have coaches, they have agents, they have mentors. These people are leading them astray. And if we have athletes that are testing positive from certain systems, those managers should also be disqualified," said Eyestone. Should Federico Rosa be worried?
