Conner Mantz

It's been a dramatic week in the world of distance running and Michael and Jessy are here to break it all down.

The biggest headline: Conner Mantz, the American marathon record holder who was one of the most anticipated starters at this year's Boston Marathon, has officially withdrawn with a stress-related injury. It's a significant blow ahead of what was shaping up to be one of the most exciting Boston fields in years.

On a more uplifting note, BYU freshman Jane Hedengren continues to rewrite the record books — this time at Stanford, where she clocked 30:46.8 in the 10,000 meters in her very first attempt at the distance, shattering the NCAA Women's record and slotting in at number seven on the US all-time list. She's 18 years old. Remember her name.

It was also a huge weekend for 5K records. French star Jimmy Gressier ran 12:51 in León — just two seconds shy of the world record — and set a new European Road 5K mark in the process. Meanwhile, 62-year-old Clare Elms did something arguably even more remarkable, running 17:45 to smash her own age group world record by 20 seconds. Her age-graded score? 104%. Yes, really.

Then there's the story that genuinely stopped us in our tracks: Clarke Reynolds, a 45-year-old runner from England with just 5% vision, is preparing to run the Brighton Marathon on April 12th guided entirely by remote volunteers via RayBan Meta smart glasses and the Be My Eyes app — with no in-person guide alongside him. It's a genuine world first, and we're already planning a follow-up with Clarke after the race.

And the episode closes on a frustrating note. Albert Korir, the 2021 NYC Marathon champion, has been handed a five-year ban after testing positive three times for CERA: a synthetic blood booster in the same family as EPO. All his results from October 2025 onwards are disqualified, though he retains his 2021 title. It's another painful reminder of the doping cloud still hanging over elite distance running.

A relatively quiet weekend in track, though there’s still plenty to dig into with Chris Chavez, Kyle Merber, and Preet Majithia.

“I've heard over and over that you have to respect the distance. I kind of understood that, but you need to experience it to have respect for it and the emotional waves that you go through during it. I had heard that and it made sense to me, but the true understanding of that hit later. That was humbling a little bit. It’s not an easy race. You can't fake a marathon.”

My guest for today's episode is Kylie Mantz. If that name sounds familiar, yes, she is the wife of CITIUS MAG Podcast regular and U.S. marathon record holder Conner Mantz. But beyond that, Kylie is coming off a year in which she walked on to BYU's track team and can call herself a marathoner now after making her debut just a couple days ago with a strong 2:43 victory at the Two Cities Marathon in Fresno, California. 

Kylie didn't run much in high school. In fact, she only started running consistently in the last two years or so. At first, it was just to understand her husband's world and then because she realized that she could belong in it. Fast forward to this year and she's raced in a BYU singlet, trained under coach Diljeet Taylor, and ran 34:57 for 10,000m on the track. Then after that, she's taken super well to the roads all while wrapping up her degree in elementary education.

What I love about this conversation is that her path is unconventional and refreshingly honest. She learned the sport from scratch with the occasional lessons from Conner and then found the confidence and spark to chase the U.S. Olympic Trials qualifier in the marathon. That's 2:37. She's proving that it's never too late to start and to dream big.

Conner and Kylie Mantz are redefining what it means to chase big dreams as a team.

They’re two runners with one purpose–moving stride for stride through life.

Conner Mantz has become the new standard-bearer for American marathoning. After winning the 2024 U.S. Olympic Marathon Trials and placing 8th at the Paris Olympics (2:08:12), he stunned the running world in 2025–running 2:05:08 for 4th place at Boston, winning the Beach to Beacon 10K in a course record time of 27:26, and setting the American marathon record of 2:04:43 at the Chicago Marathon. 

His career arc, which was shaped by BYU coach Ed Eyestone’s patient approach, reflects eight years of steady growth from NCAA champion to global contender.

Kylie Mantz, meanwhile, has forged her own remarkable path. 

A latecomer to competitive running, she joined BYU’s women’s distance program in 2025 and quickly ran 34:57 for 10,000m and 16:49 for 5000m–astonishing progress for someone who didn’t run track in high school. Her joy-driven approach, grounded in curiosity and consistency, mirrors Cennor’s faith in long-term development.

Their parallel journeys (Conner’s disciplined pursuit of podiums and records; Kylie’s joyful rise into Division I competition) intersect in a shared belief that running is both art and anchor. 

Together, Conner and Kylie Mantz are proving that love, faith, and discipline can fuel world-class performance.

Fresh off his American record-breaking finish at the Chicago Marathon, Maurten athlete Conner Mantz joins us for a special edition of The Drop. We talk about fueling and training and get the behind the scenes story of his finish at the Olympic Trials. Also, his great grandfather flew with Amelia Earhart across the Pacific, so that's cool. Thankfully, he picked the right ocean.

“Whether it's true or not, that's what I’ve got to believe. That’s the faith I’ve got to have moving forward. Regardless of what other people say, or what other people think, there is power in truth and being honest with myself. There's got to be faith and there's got to be belief that I not only can close that gap, but that I am in that tier and I can compete with the best.”

My guest for today's episode is Clayton Young. While Conner Mantz's 2:05 may have stolen the headlines, Clayton Young once again proved why he belongs in any conversation about the best marathoners in America. On a competitive day in Boston, he ran 2:0:7:04 – nearly a full minute personal best to finish seventh overall, tying his highest ever finish at a World Marathon Major. He did it despite a calf cramp at mile 20 and on an up and down lead up that included some frustrating half marathon results.

But that's the kind of thing about Clayton's success, quiet consistency, big stage composure, and a resilience that keeps him right alongside the best, including his training partner and Olympic teammate, Conner Mantz. This Boston result marks their fourth straight marathon finishing as the top two Americans in every field, and every time Clayton Young shows up.

In this conversation, we get into the Boston Marathon as it unfolded, what was actually going through his head when that mile 20 move got made, when that cramp hit, and why he's so good at staying in the mix.

Jason and Kevin quickly recap the Boston Marathon and discuss the performances of John Korir, Sharon Lokedi and Conner Mantz. Then, they preview the London Marathon and analyze Faith Kipyegon's sub-four mile attempt.

“It became, ‘No, I’m 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.’ I’m 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 I’d 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 Khannouchi’s American record, and the big step forward in American distance running.
