In a performance that underscored his rising stature in American distance running, Conner Mantz delivered a personal best of 2:05:08 at the 2025 Boston Marathon, finishing fourth and narrowly missing a podium spot by just four seconds. This time stands as the second-fastest ever recorded by an American on the storied Boston course, trailing only Ryan Hall’s 2:04:58 from 2011.  

A Race of Strategy and Resolve

Mantz, 28, positioned himself strategically within the lead pack for much of the race. However, at the 20-mile mark, Kenya’s John Korir executed a decisive move around Heartbreak Hill, opening a 20-second gap that would eventually extend to nearly a minute.   Korir went on to win the race in 2:04:45, the second-fastest winning time in Boston Marathon history.

As Korir surged ahead, Mantz found himself in a fierce battle for the remaining podium spots with Tanzania’s Alphonce Simbu and Kenya’s Cybrian Kotut. The trio remained tightly grouped as they approached the final stretch on Boylston Street. Despite a valiant effort, Mantz was outkicked in the last 300 meters, finishing just behind Simbu and Kotut, who both clocked 2:05:04.

Reflections on a Career-Defining Race

After the race, Mantz reflected on the experience:

“I made my hard move and they responded as if I wasn’t there making a move. So it was a little bit humbling,” Mantz said. “Missing it and getting outkicked for the last 300 meters is a little bitter. It’s still probably the best race I’ve had.”  

This performance marked a significant improvement over his previous personal best of 2:07:47, set at the 2023 Chicago Marathon, and his 11th-place finish at the 2023 Boston Marathon with a time of 2:10:25.  

Building Momentum

Mantz’s Boston performance continues a series of impressive results. In January, he set a new American half-marathon record by finishing the Houston Half Marathon in 59:17, breaking Ryan Hall’s 18-year-old record.  

His consistent excellence on the road has solidified his status as one of America’s premier long-distance runners.

Mantz’s achievements not only highlight his personal growth but also signal a resurgence in American distance running. As he continues to build on his successes, fans and fellow athletes alike will be watching closely to see how he performs in upcoming international competitions.
