In this episode, Dominic sits down with Alex Ostberg to distill the three biggest lessons from 2025 and set the framework for a better 2026.

They unpack why you sometimes have to “throw out your long-term plans,” how to invest in preparedness without trying to predict the future, and why embracing voluntary struggle is the best training for the inevitable hardships life will bring.

They also talk about a hard truth: you’ve already achieved goals you thought would make you happy — and why joy, fulfillment, and “a string of good days” matter more than chasing the next milestone.If you’re trying to make 2026 your breakthrough year in running, business, or life, this conversation will rewire how you think about goals, uncertainty, discipline, and what success actually costs.

Most people see Anna Sitar as a creator. Fewer people know she’s quietly stacking endurance goals, like marathons, long training blocks, and now Ironman-level ambitions, to show what happens when you commit to something long enough for it to change how you think, work and live. 

Anna is a content creator and influencer known for her lifestyle vlogs, relatable content and warm and engaging personality.

Her dynamic “I Don’t Want It” TikTok series has propelled her to incredible media heights; she has over 11 million followers on TikTik and over 1.5 million on Instagram.

Anna is a Mechanical Engineering undergraduate from Western Michigan University. She moved to Los Angeles in 2019 to pursue her master’s, and it ultimately fueled her career as a content creator. 

Anna is the founder and creator of the A N X N A clothing brand, and has worked with companies like Dior, Louis Vuitton, Delta, Amazon and Google. 

She is also slowly building up her endurance athlete profile these past few years: she recently completed the New York City Marathon after running the Honolulu Marathon in 2024. According to recent activity, she is training for an ironman, working to become a more well-rounded long distance athlete. 

Because of that, Anna’s story is a reminder that running doesn’t have to be about times or podiums to be meaningful. Sometimes it’s just a place to test who you’re becoming next.

Marcelo Mantecon is Florida’s all-time 5,000m high school record holder, a Nike Indoor National Champion, and an NXN finalist. And he’s only a junior in high school.

Marcelo joins the show after a soaring spring and fall season for Belen Jesuit Preparatory School in Miami, Florida, that saw him cap it off with a 4th overall finish at the Nike Cross Nationals (NXN) on December 6, 2025, with a time of 15:05.

In September, he etched his name into the Florida High School Boys XC record book, running a 14:35.25 at the Southern Showcase in Huntsville, Alabama, becoming the fastest boy to do so at the distance in the state. He then took that even lower in October by running a 14:33 in the New World Fall Spectacular.  

As a sophomore last year, he was named Florida’s Gatorade 2024-25 Boys Cross Country Player of the Year. He won the 5000m National Title Indoors in March of 2025 as well. 

His PRs include 4:15.83 for the mile, 8:16.86 for the 3000m indoor, 8:49.78 for the 2 mile outdoor, 14:14.38 in the 5000m indoors, and 14:33 in the 5000m for XC.

Records show you how fast he is. We’re here to dissect how he thinks; the discipline behind the breakthroughs, the pressure of carrying expectations, and what it takes to chase national greatness while still being a high school junior.

Are we watching the rise of the greatest distance running teammate duo in history? 

Ethan Strand and Parker Wolfe are well on their way to grabbing that title, and their next stop is with Team USA for the World Cross Country Championships.

Parker recently won his first professional national title at the 10,000m XC championship in December; Ethan won the 2,000m in electric fashion. Both runners are from the University of North Carolina and now run professionally for the Swoosh Track Club under coach Mike Smith.

Ethan is the NCAA Men's Indoor 3000m record holder, having run a 7:30.15 back in 2024; his mile PR is also a sizzling 3:48.32. Parker won the 2024 5,000m Outdoor NCAA Championship, and ran his impressive 29:16 at the Glendoveer Golf Course in Portland recently to secure first in a competitive USATF championship field. Parker has PRs of 3:48 in the mile on the road, 3:34 in the 1500m, and 13:10 in the 5,000m. 

The boys are back to show how elite confidence is built, how teammates become rivals, and how records are meant to be broken.

Anyone can catch lightning in a bottle once. 

Kelly Christensen is proving that he can repeat success over and over, as he just won back-to-back national high school cross country titles at NXN, and is clearly on the Mount Rushmore of high school distance coaches.  

The Niwot boys cross country team just won a second consecutive national title on December 6 in Oregon. Their 61 points set a record for the best team score ever recorded at Nike Cross Nationals, which began in 2004.

The boys were led by Quinn Sullivan (5th with a time of 15:09), Hunter Robbie (6th), Ryder Keeton (33rd), Jude Ritzenhein (40th), and Gabe Marshall (60th). The girls team came in second. 

Heading into this season, Coach Kelly had guided the Cougars to 12 total state championships. You can add to that number after another dominating season this year. 

He recently was recognized on a national level by being named MileSplit's Coach of the Month in November 2025 for his program's continued excellence.

If you want to understand how elite programs stay elite, Kelly Christensen is back on the Running Effect. No fluff or preamble: he’s opening up about another dominant and historic season for the Niwot Cougars.

What if the habits you’re most proud of, like discipline, the mileage, and the wins, are quietly working against you?

Alex Ostberg returns to the show to sit down with Dominic and unpack the ideas behind his four most recent Substack essays, each challenging a deeply held assumption in running and high performance.

They tackle the popular mantra “the way you do one thing is the way you do all things.” Alex argues that greatness isn’t about equal intensity everywhere, but intentional trade-offs, seasonal focus, and knowing what deserves obsession.

From there, they discuss training load and why not all miles are created equal. Alex explains why injury risk is less about total mileage and more about how that load is built.

The guys then take aim at a sacred post-workout ritual in Cooldowns Are Overrated. He reframes recovery around what actually matters most: refueling, rehydration, nervous system reset, and social decompression, rather than mindless extra miles on tired legs.

Then they talk about the psychology of success in When Winning Stops Feeling Good, exploring why anticipation often feels better than achievement, and how rising expectations can quietly drain joy from performance. 

If you want to train smarter, think deeper, and understand the real costs (and rewards) of chasing excellence, this episode will change how you run, recover, and define success.

Sharon Lokedi set a Boston Marathon course record, ran a 65-minute half marathon, and stepped foot on another NYC Marathon podium. 

 She didn’t just have a good year in 2025, she had the kind of season that rewrites expectations for the future of women’s distance running, and her 2:17:22 course record at Boston can attest to this.

Sharon’s most recent success came at the New York City Marathon, where she came in second place with a time of 2:20:07; this was her third career podium finish at NYC, as she won the whole thing in 2022 during an impressive marathon breakout performance.

The year 2025 also saw her win the NYC Half Marathon in an event record time, and then set a PR in the 13.1 distance with a 1:05:00 at the Copenhagen Half. 

She came in an impressive 4th place in the marathon during the 2024 Olympic Games in France, running a 2:23:14. Prior to that she was a stalwart in the collegiate ranks while running at Kansas, winning the 10,000m at the 2018 NCAA Outdoor Championships. 

After a Boston course record and a world-class season, she’s stepping into the next chapter with more clarity, more confidence, and more momentum than ever before. Sharon Lokedi’s story is unfolding in real time, and we are here to witness it.

Whether you’re a shoe nerd, a data-driven athlete, or just curious about what makes the Glycerin Flex so different, this is required listening. If you’re interested in delving into the experience of the future of cushioning in running straight from the source, this is the place to be.
