The CITIUS MAG Podcast | A Running + Track and Field Show

It became, No, Im attacking this marathon. It was more of an assertive mentality. Hearing the crowds roar, I was fighting for the podium It was like, This is it. Im doing what I set out to do and I feel great. It was a very special moment. I was pretty zoned in, but I enjoyed it and Id love to live through it again.

On a brisk April morning in Boston, Conner Mantz delivered the marathon breakthrough that he's been waiting for. Running fearlessly from the front, Mantz surged through the Newton Hills, hung with a deep pack through about 40 kilometers, and stopped the clock in 2:05:08 seconds a massive personal best and the second-fastest time ever run by an American.

Boston is not a record eligible course, but this was a major performance. He finished fourth overall and just four seconds off the podium in one of the fastest editions in Boston Marathon history. It was a performance that firmly placed Mantz among the world's elite, showing he's not just America's top distance talent, but he's now a serious contender at the sport's highest level too. This came just months after breaking the American record in the half marathon in Houston and just weeks after backing that up with a 59:15 in New York. It's been a big year and it's only April.

In today's episode, Conner and I talked through that Boston effort from studying past races, to covering all the big moves, to racing for time and place. We also dig into what's next, chasing Khalid Khannouchis American record, and the big step forward in American distance running.

"What do we need to do to win Boston? We said, 'Be patient from the start and then at 20 miles, make a move.' We were good and we made it."

After taking a fall right off the starting line, John Korir regrouped, surged at mile 20 with a jaw-dropping 4:41 split, and never looked back crossing the line in 2:04:45, thesecond-fastesttime in Boston Marathon history. With the win, he joins his brother Wesley on the list of Boston champions and mightve just stepped to the front of the global marathon stage.

Korir has now won Chicago and Boston both in dominant fashion and since Kelvin Kiptums tragic passing and Eliud Kipchoges regression, hes making an strong case as the best marathoner on the planet right now.

In todays episode, we talk about thatsavage21st mile, what it means to carry the Korir family legacy forward and whether a world record attempt might be the next big move.

The 2025 Boston Marathon promises an exciting blend of redemption stories, debut intrigue, and head-to-head rivalries across both elite fields. On the men’s side, defending champion Sisay Lemma returns after last year’s audacious front-running victory, facing off against 2024 Chicago champ John Korir, two-time Boston winner Evans Chebet, rising Kenyan Daniel Mateiko, and U.S. hopeful Conner Mantz. Other contenders include Lesotho’s Tebello Ramakongoana and Americans Clayton Young and CJ Albertson, each hoping to outlast the pack or capitalize on race-day chaos.

In the women’s race, Hellen Obiri is chasing a rare three-peat in Boston, entering as the clear favorite despite a strong field. She’ll be challenged by past podium finishers Amane Beriso and Sharon Lokedi, 2:16 marathoner Yalemzerf Yehualaw, and rising marathon star Irene Cheptai. The American field is led by Keira D’Amato in her Boston debut, Emma Bates returning to form, and Dakota Popehn riding Olympic momentum. Young talents like Gabi Rooker, Jessica McClain, and Jackie Gaughan round out a promising domestic squad, with veterans Des Linden and Sara Vaughn adding experience to the mix.

Cooler temperatures, slight winds, and the Newton Hills promise another unpredictable Patriot’s Day. Tactics, toughness, and timing will determine who claims the tape on Boylston.
