Connor Mantz is the American marathon record holder, but his journey to the top hasn’t been straightforward.
After a breakout 2025 season that included a record-breaking 2:04:43 at the Chicago Marathon, Mantz looked poised for even bigger things. But a sacrum stress fracture forced him off running for nearly three months.
In this episode, Alex Cyr sits down with Mantz to talk about his recovery, his build toward the 2026 Boston Marathon, and what it takes to compete with the best marathoners in the world.
