Conner Mantz Finishes Fourth, Sets Second-Fastest U.S. Time at Boston Marathon

Conner Mantz delivered a historic performance at the 2025 Boston Marathon, finishing fourth with a time of 2:05:08—the second-fastest marathon ever run by an American on any course. Mantz narrowly missed both a podium finish, coming just four seconds behind second and third place, and Ryan Hall's American-best mark in Boston from 2011. Despite his disappointment at missing the podium, Mantz's effort was widely praised, with his coach highlighting the achievement in one of the deepest, most competitive Boston fields. Mantz remained with the lead pack until a late surge by Kenya’s John Korir broke open the race, eventually leading to Mantz battling for second in the final stretch. His performance, along with strong runs from fellow Americans Clayton Young and Ryan Ford, marked one of the best showings by U.S. men in recent Boston history. Due to Boston’s course layout, Mantz’s time is ineligible for the official American record, but it solidifies his status as the top American marathoner and raises expectations for future races.
