“I’ve watched too many Chicago Marathons. I’ve been in too many Chicago Marathons. My experience in this race is unparalleled right now — and it felt good when it mattered on Sunday.”
Clayton Young is the top American at the 2026 Chicago Marathon, now officially the second-fastest American in history on a record-eligible course with a 2:05:23. He did it on a hamstring with a 12-centimeter tear that his doctor had recommended four weeks of rest for.
The race itself was one of the more dramatic in recent American marathon history. Vinny Mauri went to the front at 15K, dropped the pacers, and made a genuine bid for something bigger — at 30K he had 38 seconds on the rest of the Americans and was on 2:04 pace. Then it was his hamstring that started talking. He stopped several times to stretch in the final miles, the chase pack caught him. Charles Hicks surged hard trying to catch Mauri after the pacers stepped off, and Clayton simply followed before making his big move with a 4:38 mile.
Clayton was chasing Connor Mantz’s American record of 2:04:43 the whole time since he he called that shot publicly weeks ago — and it didn’t happen. But he ran his fastest time ever, finished seventh overall in a field that included the likes of Amos Kipruto and Jacob Kiplimo… again, he did it all while managing a torn hamstring he’d been babying for a month. He called it one of the best marathon performances of his career. I agree.
We discuss:
– The night-before meeting with Coach Eyestone
– The chaos of those Mauri miles
– The moment he decided to throw down
– The faith that carried him through four weeks nobody could have scripted
– What comes next for the hamstring, the spring, and 2027
