THE RUNNING EFFECT PODCAST

Nathan Green came to talk, and he didn’t hold back.   

The 23-year-old Adidas miler swept both U.S. 1,500m titles in 2026, and he joined Dominic to defend those wins against the couch warriors who call them too slow to count. He walks through his championship résumé and fires back at critics, including a plant-selling Instagram hater he now looks forward to hearing from. 

Nathan names Hobbs Kessler as the best American 1,500m runner right now. He also makes his case for lifetime doping bans, and he and Dominic...

Klaudia Kazimierska didn't just finish 2026. She owned it.In her first season under Jerry Schumacher, the Polish middle-distance star closed with three straight wins: the Diamond League Final in Brussels in a world-leading 3:54.05 national record; the inaugural World Ultimate Championship in Budapest; and Athlos London. Klaudia walks Dominic through it all, from the imposter syndrome that hit as she crossed the line first in Brussels to the "perfect race" she finally executed in Budapest after years of chasing one.The real story starts earlier, though. At 20, Klaudia was burned out in Poland, training solo, living out of a suitcase...

Salt might be the most overhyped thing in your running bag. Alex Ostberg is back from Chicago, where Charles Hicks became the No. 3 American all time on a record-eligible course, for his monthly breakdown of the last four editions of The Rundown. He and Dominic start with electrolytes, a piece prompted by Riley Witt’s hot take. They cover why sweating actually raises blood sodium, the four dials that decide whether you need a sodium plan, and why slower marathoners face more hyponatremia risk than the elites. Next, they ask how much of your training actually serves your health. The...

Nobody builds a distance program at Harvard. Alex Gibby did it twice over 

Alex arrived at Harvard in 2017 and inherited a program that had almost never made nationals, and didn't have a single athlete setting a PR after early February. Ten years later, the Crimson men have qualified for the NCAA Cross Country Championships six straight seasons, and Gibby has coached Graham Blanks to back-to-back NCAA cross country titles and Maia Ramsden to NCAA titles in the mile and the 1500m.

In this conversation with Dominic, Gibby gets into how...

Natasza Dudek only wanted a PR. She got history instead. 

Now a junior at Ann Arbor Pioneer and the reigning Gatorade National Girls Cross Country Player of the Year, Natasza joins Dominic midway through her 2026 season to look back on the year her name went national. She remembers watching her oldest sister Zofia’s finishing kick win the 2019 Foot Locker title on a computer screen. She also explains what she learned as the youngest of three running sisters, and how weeks of workouts in the school hallways and a “feels like one degree” Brooks photo s...

The woman who breaks four minutes in the mile has probably already been born.

That's the opening claim from Professor Andy Jones, the Exeter physiologist behind Nike's Breaking2 project, and he gives her ten to fifteen years. The problem right now, he explains, is a split field: some women have the aerobic engine and the critical speed but no anaerobic reserve, while others have the speed and no endurance. Faith Kipyegon came up short on the 800m side, and Jones believes a properly paced attempt would have landed her near 4:03—a time that would ha...

After Josh Kerr's mile world record, Danny Mackey had 478 unread texts. He answered about 20 of them.

The founding head coach of the Brooks Beasts Track Club joins Dominic at the end of the best season of his career. Josh Kerr broke the mile world record in London, about an hour after Brandon Miller won the 800m. Mackey still says he hasn't really reflected on any of it. He explains why: after 217 NCAA coaching rejections, he's still the guy who worries he could lose his job.

Dominic opens with a...

Some coaches chase talent. Todd Witzleben builds it.

When Witzleben took over at Manhattan University in June 2025, one regional ranking had the Jaspers 41st out of 42 teams in the Northeast, with six men on the cross country roster. A year later, there are 16, and he's talking about a 7:25 time in the 4x800 relay. Dominic sits down with the former Buffalo associate head coach to talk through the rebuild: from leaving a MAC program when a promotion request got laughed off, to the alumni who still care about a 1973 NCAA indoor title and a 1974 American re...

Vinny Mauri got drug tested at a Planet Fitness.

Five months after his 2:05:54 marathon at Glass City made him the fastest marathon debutant in American history, the self-coached Ohioan returned to the show just days before his second marathon in Chicago.

Dominic starts hot. Vinny explains why he emailed USADA himself the day after Toledo, why he feels honored rather than offended by the doubters, and how his first official test finally happened at the treadmill he uses right in front of the lobby. Then the training gets absurd: a 4...

Four hundred straight dual meet wins don't happen by accident. 

Sean McCafferty, entering his tenth year as head cross country coach at Christian Brothers Academy (CBA) in Lincroft, New Jersey, joins Dominic to unpack the culture behind one of the most storied programs in high school running. Sean ran at CBA before competing at Princeton, and he later took over the program from Tom Heath, who led it for 45 years. He talks openly about the years he spent trying to coach like someone else before realizing he was better as himself.

H...

Ethan Strand is a national champion who still believes he finished second.

He found out Jonah Koech had been busted for doping in the middle of a treadmill run, when Parker Wolfe tapped him on the shoulder, and his first reaction was anger. In this conversation, Ethan tells Dominic why the title still feels strange, why he feels worse for Hobbs Kessler, and why he thinks a positive test should end a career. He also covers the unglamorous side of racing clean: updating his whereabouts before dinner, keeping the last pills from every supplement ba...

Aleksander Lingauer is stepping away from running. He says it out loud here for the first time.

This one was recorded in person in Columbus, the fourth time he and Dominic have sat down together and the first time with no race waiting on the other side of it. Near the end, Aleksander announces that he is pausing his racing indefinitely. The reason is a book—the account of his 419-day solo walk across Europe, shelved when he signed as an athlete, now being finished. It arrives next year.

Be...

Marcelo Mantecon has spent his whole career as the young guy. Not anymore.

The Belen Jesuit senior joins Dominic for the next episode of our Fleet Feet series leading into the Brooks Cross Country National Championships, and he arrives carrying something he didn't have last December: a target. He talks about welcoming the pressure that comes with being the top returner, about what he absorbed watching Jackson Spencer stay calm on start lines while his own nerves churned, and about learning to convert that nervousness into excitement instead of dread.

Behind Graham Blanks' 12:47 5K & 7:27 3K: 6:00min Easy Days, Training Alone & Racing Jakob Ingebrigtsen 

Graham Blanks can tell you exactly what he did wrong in every race he ran this year.

Monaco is the exception, and the one he's most excited about. It's the only race this season he finished and then couldn't sleep—his own heuristic for a good one—and the first time he really put down a fast 400m at the end. After that, closing hard got easier, because he knew he could.

Two guys named Dom, one goal, two completely opposite ways of getting there.

Dom Fusco returns to the show for the first time since March 2023, and this one isn't about his cardiac arrest—it's about the question flooding Dominic's DMs: how do you build real muscle without giving up your running times? Fusco has done it from the football side, Dominic from the distance running side, and both are now chasing sub-3 marathons this fall.

They open where the Austin hybrid scene actually lives: peptides, HGH, and TRT. Fusco has never t...

Dominic sits down with Carter Cutting, Isaac Hedengren and Tayvon Kitchen a day after the Cougars opened their season in Terre Haute. It starts as a debate—Jakob versus Kerr; whether Hawker belongs in that tier; whether one down year should count against anybody—and the three of them push back hard enough that Dominic ends up defending his take alone.

From there it turns into the story behind New Standard, the channel they built after an indoor season of workouts none of them thought were possible. Coach Eyestone hated the cameras at first, and th...

Alex Hutchinson ran his 1500-meter breakthrough because a timekeeper called the splits wrong.

He’d been stuck at just over four minutes for three years. Then, in one indoor race, a mistimed clock told him he was running three seconds faster than he was—and he ran 3:52, then 3:49, then 3:44 across the next two months. His old coach went through the logs looking for the reason. There wasn’t one.

That story sits at the center of this conversation with the physicist-turned-journalist behind Endure and the Sweat Science column at Outsid...

Hans Troyer led Western States for 62 miles, DNF’d, and still calls the day a win. 

Eight weeks later he was on the CCC podium, which tells you most of what you need to know about how he metabolizes a bad race. Dominic welcomes back the 26-year-old for the first time since before his 2025 Western States debut, and Hans admits the stretch since has felt like three years crammed into one.

He traces the self-belief back to Bandera in 2024, when a few coachless months in Georgia were enough to prove...

Nobody quits while they're ahead.

Alex Ostberg is back for the guys’ monthly walk through of The Rundown, and this one runs from the foundations of the sport to the psychology of knowing when to walk away.

They open with ten things Alex wishes he knew as a high school runner—the talk that started this whole collaboration, and one he still finds himself repeating to professionals a decade later. Why consistency beats perfection. Why a plateau isn't a bug in the program. What quietly rots a team culture from the...

Rocky Hansen spent the offseason quietly begging Habtom Samuel not to turn pro.He lost to Samuel twice—the NCAA cross country final in November and the outdoor 5,000 in June—and his reaction to Samuel leaving wasn't a relief. It was a feeling of disappointment at losing the rematch. That instinct sits at the center of this conversation, recorded a few weeks into Rocky's final collegiate season.They get into the race he's proudest of, which he also lost. Samuel got him by a second and a half, and he calls it the best tactical race of his NCAA care...

Jordan Hasay Hogan never officially retired.

She was the most hyped teenager in American distance running. She was a Foot Locker champion as a freshman, she acquired eight California state titles, was an Olympic Trials 1500m finalist at sixteen—and then went on to run a 2:20:57 marathon in Chicago. In this conversation, she opens up about the Nike Oregon Project years in a way almost nobody has.

She walks Dominic through the actual training: 115-mile weeks, 25-mile long runs with fifteen at six-minute pace on an altitude...

Colin Sahlman finished 151st at NCAA cross country as a freshman. Four years later he left college with three national titles.Colin returns to the show for the first time since high school, now a Nike athlete training with Swoosh TC in Flagstaff. He walks through the part of the story most people skipped: the freshman year that humbled him, the sophomore cross country season where he didn't even make the travel squad, and the junior year where he missed the outdoor 1500 final and coach Mike Smith floated calling the season early. Colin said no, asked to run the 800...

Jess McClain almost skipped her first Foot Locker Nationals for a high school dance.

Her coach talked her out of it, and she went on to become one of only 27 girls in the meet's history to make all four national finals—2006 through 2009, alongside classmate Emily Sisson.

Sixteen years later, she's the fastest American woman ever to run Boston.

Jess kicks off the Call Room: Golden Ticket Edition, presented by Fleet Feet, leading into the Brooks Cross Country National Championships. She and Dominic start with the...

You can't out-tough sleep.

That's Todd Anderson's whole argument, and he makes it as a guy who tried. A walk-on fullback at Michigan State who signed with the Rams of the NFL in 2012, Todd spent a decade in strength and conditioning before deciding the highest-leverage hour of an athlete's day is the one they spend unconsciously. 

He's now co-founder and CEO of Dream Performance & Recovery and is working toward a PhD in sleep psychology.

Dominic caught him marathon mid-buildup—Todd's training for Chicago, Dominic for C...

Riley Witt says a hot bath beats a microdose of EPO.

That's where this one opens, and it doesn't slow down. Riley walks through passive heat training—45 minutes at 104 degrees, four or five times a week, and the plasma volume adaptations that come with zero skeletal strain. He explains why water cooks you faster than a sauna, why going straight from a run into the heat multiplies the effect, and why a hot bath before bed will wreck your sleep instead of helping it.

From there: electrolytes as the mo...

Andreas Almgren just won European gold by lapping half the field—and six days later, he announced he's stepping up to 26.2 miles for the first time.

In this episode, recorded mid-marathon-buildup with the aches to prove it, Almgren breaks down the decision to make his marathon debut at the TCS New York City Marathon on November 1, and why he chose the toughest, slowest Major Marathon over a flat time-trial course like Valencia. 

He explains the front-running gamble that produced his historic 27:23.44 in the 10,000m in Birmingham—a 3:17 opening kilometer that...

Most runners aren't training too hard. They're spreading the hard work too thin.

Marius Bakken has spent thirty years proving it. The Norwegian physician and two-time Olympian pricked his finger more than 5,500 times—on himself, on training partners, on runners in Kenya—to map one narrow band of intensity, and the framework he built from it is what the world now calls the Norwegian Method. This conversation is the compressed version of his new book, The Norwegian Method Applied, out now on Amazon with a li...

He built a world-class pro group in Baltimore. Then he left it for a college roster of 30. 

Five years after his first appearance on the show, Cory Leslie returns as Ole Miss's new associate head cross country and assistant track & field coach, fresh off nearly five years building Under Armour's Mission Run Baltimore into a group that produced Olympians and World XC medalists from a city nobody expected it from.

He walks Dominic through how fast it all happened: a casual conversation with Connie Price-Smith at USATFs in New Y...

The most famous voice in running almost quit before he ever got fast. It took a bad workout (and a girlfriend on the verge of dumping him) to turn Chris Bennett into Coach B.

Nike's Global Running Head Coach and the voice in millions of ears on the Nike Run Club app sits down with Dominic for a conversation about what actually builds greatness—and it's not what you think. Coach B traces his path from "incredibly lazy" college runner at UNC to architect of one of the great high school dynasties at Christian Brothers Academy, where hi...

Jemma Reekie doesn't remember most of her records—she just ran and found out later.

The Scottish 800m/1500m star joins Dominic fresh off a fifth-place finish in the stacked Birmingham 2026 Euro 800m final, and opens up about a career that's been defined by extremes: three British indoor records broken in eight days as a 21-year-old who didn't even know what the records were; a fourth-place finish at the Tokyo Olympics decided by 0.09 seconds; and a Paris 2024 Olympics that looked like her best shot at a medal on paper but ended without even a fi...

In fact, the urge to prove your fitness before race day might be the very thing that breaks you.Alex Ostberg is back for our monthly recap of The Rundown, his weekly newsletter that lands in your inbox every Thursday.

Your body doesn't know the difference between Coca-Cola and watermelon. And according to registered sports dietitian Cortney Berling, that might be the most freeing thing a runner can learn.

Back for her third appearance on The Running Effect, Cortney joins Dominic to dismantle the food rules holding runners back, starting with the sport's most controversial question: does weight loss actually make you faster? Her answer is a masterclass in why general nutrition advice fails athletes, especially female ones. 

The guidelines on your food label were built around a 154-pound r...

Josh Kerr didn't chase the mile world record, he created it. And the man who spent six years helping him build the mind to do it is finally telling the story.

Jose Maresma is Kerr's sports psychologist, a clinical exercise physiologist with 35 years of experience spanning the Olympic Training Center, the NFL, NBA, special operators, ER doctors, and CEOs. Their partnership started with a pickaxe: Maresma invited Kerr to his men's group, where the Olympic medalist cracked through four inches of ice at six in the morning and realized the anxiety felt exactly like st...

Pete Julian didn't beat cancer—he survived it, and that distinction shapes everything about how he coaches.

The Union Athletics Club founder sits down with Dominic for one of the most reflective conversations in the show'shistory. Julian opens up about coaching across cultures—helping Suguru Osako escape Japan's ekiden machine, swapping pep talks for pure logic with Germany's Koko Klosterhalfen, and why Shannon Rowbury remains the most impressive athlete he's ever coached.

He makes a case few pro coaches will: America's best coaches aren't in the NC...

Trenton Sandler didn't care about running until his senior year of high school. Now, he's a 3:42 1500m man with 130,000 followers watching every step.

The Arkansas transfer joins Dominic the day before his move to Fayetteville for a conversation about one of the strangest paths in the NCAA. A lifelong soccer player who only ran track to stay in shape, Trenton parlayed a 1:55 time in the 800m into an SEC roster spot, spent two years buried in injuries, then watched his LSU distance group collapse from 12 guys to three. 

He left th...

You don't replace Mike Smith. You carry forward what he built, and Jarred Cornfield is proving that's exactly how dynasties survive.

Entering year two as NAU's Director of Cross Country and Track & Field, Cornfield returns to the podcast as another Flagstaff fall arrives. He opens up about the transition from nine years as Smith's assistant—resisting the urge to prove himself, leaning on his mentor (still in town, still a phone call away), and practicing the same pressure-management he preaches to his athletes.

The conversation digs into the anatomy of...

Dr. Bill Evans admits the post was rage bait. But the science underneath it isn't.

Dominic opens by asking about Evans' claim that you can run faster with low testosterone, and Evans cheerfully cops to baiting the testosterone crowd before laying out the actual evidence. 

Two things can be true at once: train hard for years and your T drops, and your performance keeps climbing anyway. He walks through Anthony Hackney's overtraining research, the 80-kilometer-per-week marker where androgen deficiency starts showing up, and the diffusion-distance argument for why the bes...

Ashley Bastron just had the best year of her coaching career. Then she quit, and she's never felt more at peace.

In this episode, Dominic sits down with the former Wake Forest Associate Head Coach who guided the Demon Deacon women to their first NCAA Cross Country Championships since 2006, coached three All-Americans and two ACC champions in 2026, and then announced in July that she was stepping away to become a full-time clinical mental health counselor. 

Her reason cuts deep: in an NCAA increasingly built around money and results, she c...

Six weeks ago, Nate Mountain’s championship dreams died on the last lap of the NCAA final. 

Turns out they were just getting started.

The newly-minted U.S. steeplechase champion joins Dominic to unpack the wildest six-week swing in the sport: a ninth-place “mental implosion” at NCAAs, followed by a full reset in Charlottesville (fewer workouts, more coffee walks and pick-up 21 against a fifty-year-old street baller), and a nothing-to-lose dive across the line at Icahn Stadium to win his first national title by 0.07 seconds.

Nate takes us in...

Brandon Miller is done being overlooked. 

The Brooks Beast is riding the hottest streak in American 800m running: four straight wins, including a takedown of world indoor champion Cooper Lutkenhaus at the Prefontaine Classic, and a 1:42.19 stunner over Olympic champion Emmanuel Wanyonyi in London that made him the fifth-fastest American in history. 

In this conversation, Dominic and Brandon dig into the season that turned a former prodigy (nine AAU national titles and maybe the most-watched kid in FloTrack history) into the man of the moment.
