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

“I don’t live to run. I run to live. And the decision was: let’s just both stay home.”

My guest for today’s episode is Conner Mantz — the American record holder in the marathon and for the first time on this podcast, a dad. He is days out from the TCS New York City Marathon, where he will race for the first time since breaking the record in Chicago last October. The twelve months in between have been the hardest of his career.

Here is what happened. He ran 2:04:43 in Chicago, felt great, went for a flush jog the next day, and then spent the following eight months navigating two sacral stress fractures. It knocked out his entire spring. US Cross Country, World Cross, Boston — all watched from home. He returned to action this summer and most recently raced World Half Marathon Championships in Copenhagen in September. He ran a bit over his head and blew up badly and finished twelfth.

He is now in the best shape he has been in since the record. Not carrying fitness from a long peak — coming into it. His biggest workouts actually have come 10 to 15 days out.

In this conversation we go through the injury timeline, what he should have done differently, watching Boston from home and what he thought he’d run. He’s open about the complicated emotions of watching Clayton Young chase his record in Chicago, what he saw up close in Andreas Almgren’s training that floored him and what will make for a good day in New York.

“Going into my first one, we played it pretty safe. We really wanted to work on strength and didn’t touch much work faster than 5:00/mile pace. Then going into Boston, we pushed the envelope a little bit — like, okay, we’ve got one on the board, let’s go for a big one.”

We’re kicking off our pre-NYC Marathon interviews and my guest for today’s episode is Joe Klecker — an Olympian, 2026 Boston Marathon top-ten finisher, and in eleven days, a returning TCS New York City Marathon competitor. He ran 2:05:56 at Boston in the spring, which puts him in the conversation with everyone we’ve been talking about this fall, and he goes into New York off what he described to me as his best training block yet. There were seven weeks above 130 miles and a peak at 135.

This is a training-heavy discussion for the freaks. I think the part I enjoyed the most was thinking through with Joe on his theory of what a former 5K and mile specialist has to do to actually become a marathoner from the inside out?

That was him. He’s spent the last two marathon builds trying to rewire his physiology for an event that is fundamentally different from everything he trained for across the first fifteen years of his running life. He ran 60:02 at the NYC Half in the spring. He shares basically all of it on Strava and through his Suunto posts on Instagram.

So for the training obsessives, we talk mileage, the fueling evolution from New York to Boston to now, what he wants to fix from last year’s race, how he thinks about the OAC internal competition with Patrick Kiprop and Ryan Ford, who are all set to race alongside him.

LA28 OLYMPIC MARATHON QUALIFICATION DETAILS ARE HERE.

World Athletics has outlined how athletes can qualify for the 2028 Olympic marathon:

- Qualification window: Nov. 1, 2026 – April 30, 2028

- 70 quota places per gender (down from 80 in Paris)

- Entry standards to be finalized in December

- Top 5 at a Platinum Label marathon counts toward the entry standard

- World Rankings will help fill the remaining places

- March 19, 2028: Top 55 on the filtered quota list are locked in

That last date is especially important for Team USA.

It’s six days before the U.S. Olympic Marathon Trials in St. Louis, meaning the Americans could have all three men’s and three women’s Olympic quota places secured before race day.

We broke down the rules, the Boston Marathon wrinkle, potential qualifying standards and why we feel better about the U.S. avoiding a repeat of the 2024 qualification headache.

“I’ve watched too many Chicago Marathons. I’ve been in too many Chicago Marathons. My experience in this race is unparalleled right now — and it felt good when it mattered on Sunday.”

Clayton Young is the top American at the 2026 Chicago Marathon, now officially the second-fastest American in history on a record-eligible course with a 2:05:23. He did it on a hamstring with a 12-centimeter tear that his doctor had recommended four weeks of rest for.

The race itself was one of the more dramatic in recent American marathon history. Vinny Mauri went to the front at 15K, dropped the pacers, and made a genuine bid for something bigger — at 30K he had 38 seconds on the rest of the Americans and was on 2:04 pace. Then it was his hamstring that started talking. He stopped several times to stretch in the final miles, the chase pack caught him. Charles Hicks surged hard trying to catch Mauri after the pacers stepped off, and Clayton simply followed before making his big move with a  4:38 mile.

Clayton was chasing Connor Mantz’s American record of 2:04:43 the whole time since he he called that shot publicly weeks ago — and it didn’t happen. But he ran his fastest time ever, finished seventh overall in a field that included the likes of Amos Kipruto and Jacob Kiplimo… again, he did it all while managing a torn hamstring he’d been babying for a month. He called it one of the best marathon performances of his career. I agree.

We discuss:

– The night-before meeting with Coach Eyestone
– The chaos of those Mauri miles
– The moment he decided to throw down
– The faith that carried him through four weeks nobody could have scripted
– What comes next for the hamstring, the spring, and 2027

"I’m coming away happy with taking a big swing at it. It’s better to hit the wall early than in March of ’28 or at something that matters a little bit more.”

My guest for today’s episode is Vinny Mauri. And Sunday’s Chicago Marathon was exactly as exciting as you hoped it would be thanks to him. At 15K, running 2:04 pace in his first world major, Vinny looked around, decided that was too conservative, and made a move for something he described as “astronomical”. He led the Americans by 38 seconds at 30K. He was on American record pace at mile 21. And then the hamstrings started talking, he had to stop and stretch about six times in the final ten miles, and he finished tenth in 2:06:45. He also still managed to walk away with the U.S. 30K record.

Vinny is 25 years old, still self-coached, still working at Second Sole in Niles, Ohio, now signed with ASICS, and now in two marathons has run 2:05 and 2:06 — one alone on a bike path and one in the lead pack of the Chicago Marathon where he spent the first nine miles fist-bumping his competition (who maybe didn’t hit him back) and making faces at his family on the sidelines.

He says his third marathon will be a little different. He said so himself on Strava that he’ll plan to take it a bit more seriously. People who don’t know him might read that as disrespect for the distance. People who do know him understand it’s the opposite.

In this conversation, we discuss:

– The weekend vibe he and his girlfriend set for themselves the moment they landed in Chicago
– The start tent energy
– The Strava post that previewed everything
– The green light moment at mile nine when he decided to go
– The stops to stretch and what he was calculating each time
– The moment Clayton and Charles caught him and he waved them on
– What he’s actually going to change for the next block.
– We also get into the four hours in the drug testing room and his belated celebration for it all
