Clayton Young Reveals Hamstring Tear, Still Plans To Chase American Record At 2026 Chicago Marathon

“I called my shot. I’m confident in my ability to still chase the American record. I’ve already learned so much this build that it’s already been a success.”

My guest today is Brooks professional marathoner and Suunto-supported athlete Clayton Young, joining us two weeks before the 2026 Chicago Marathon.

Earlier this spring, Clayton finished 11th at Boston in 2:05:41 after a ten-week build that followed a significant injury and a change in sponsors. He’s spent months preparing for Chicago with a bigger goal in mind: chasing Conner Mantz’s American marathon record of 2:04:43.

Part of that ambition came from watching Josh Kerr call his shot at the mile world record. Clayton took to heart the idea of creating the conditions for a breakthrough, and he’s written the same declaration in his journal every day: “I, Clayton Young, will break the American record on October 11th, 2026 at the Chicago Marathon.”

But his tune-up at the Great North Run didn’t go as planned, and he had an MRI afterward. For the first time, Clayton shares the extent of the injury and what it means for Chicago.

We also talk about the psychology of stating his goal publicly, the data behind his training decisions, how Coach Eyestone has adapted, and what Clayton makes of Chicago competitors Charles Hicks and Vinny Mauri. He explains why this race feels different from Boston—and what he wants spectators to yell when they see him on the course.

We discuss:
– The daily journal ritual
– Having fun is a skill he has had to practice
– Josh Kerr’s mile world record as the direct inspiration for calling his shot with the American record attempt
– The contrasting psychologies with Charles Hicks
– Dr. Craig Manning and the purpose of a goal
– Abundant mentality on the field
– Coach Eyestone’s adaptations to recent success by other runners
– The data gathering from Commons Clinic, Stride, Suunto, Brooks Sports Research Lab
– The build being the best training of his career– The injury and the first public disclosure of its extent
– What it means for the 2026 Chicago Marathon
– What he learned from The Great North Run
– What to yell on course for him
