Conner Mantz: The American Marathon Record, Injury Comeback, and His Road Back to Boston
Connor Mantz is the American marathon record holder, but his journey to the top hasn’t been straightforward.

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.
