What does it take to run 603 miles in six days?

We recorded this episode live at The Running Event with Megan Eckert, who set the women's six-day world record this past May at the Gomu World Championships in France, becoming the first woman in history to break 600 miles. She also holds the women's backyard ultra world record (362 miles at Big Dog's) and somehow still works full-time as a middle school special education teacher and high school track coach.

Megan didn't come up through the traditional running pipeline. She started as an adult, dealt with undiagnosed iron deficiency for years, and figured out her approach to fueling through trial, error, and eventually working with a sports nutritionist. At 38, she's proof that it's never too late, and that eating enough is actually faster than eating less.

We talked about iron deficiency in female athletes and why "normal" lab ranges don't work for us, how to fuel multi-day events with real food (Doritos included), carbohydrate periodization without overthinking it, body image pressure on women as we age in sport, and why her supplement routine is probably simpler than yours.

This episode is brought to you by Mount to Coast, the first performance footwear brand designed specifically for ultrarunning. Their shoes feature technology built for long-distance runners, including dual lacing systems that let you adjust fit as your feet swell and endurable midsoles with cushioning that stays supportive from mile one to mile 500. Megan set her six-day world record in Mount to Coast AR Ones.

We brought the husbands on for this one. Sean Van Horn and TJ David join us to talk about eating disorders in men, disordered eating in male athletes, and how the wellness industry preys on masculine insecurity with different packaging but the same playbook.

First up: a game called Influencer or Dictator, where the guys guess whether quotes about discipline and suffering came from David Goggins or Joseph Stalin. It was harder than it should have been.

Ten million American men will experience an eating disorder. Men make up 25 percent of cases, but only 10 percent of treatment, and the shame is double because you're told you have a "women's disease." Meanwhile, gym culture sells restriction as optimization and calls it biohacking. If you put it in a spreadsheet, it's not mental illness, right? It's astrology for boys.

We trace the history from Charles Atlas selling masculinity during the Great Depression to G.I. Joe's impossible biceps to today's Ginfluencer explosion. Every masculinity crisis spawns a fitness boom. Sean shares his own eating disorder recovery, and we break down the red flags hiding in plain sight: cutting, clean eating, cheat days, earning food, no rest days. When The Rock does it, he's a brand. When your friend does it, check in.

Every January, gyms overflow and 91% of resolutions get abandoned before spring. In this episode, we trace the surprisingly ancient history of New Year's resolutions—from Babylonian harvest promises to Roman offerings to Janus—and explore why our brains are so bad at sustaining behavior change.

We debunk the myth that habits take 21 days to form (it's actually 18 to 254 days), explain why willpower is one of the least effective tools for lasting change, and dig into the neuroscience of why your cortisol-flooded prefrontal cortex might be working against you. Kylee breaks down the resolution patterns she sees in her nutrition practice—the athlete trying to drop 20 pounds in four weeks, the five-hour Sunday meal prep plans, the all-or-nothing thinking that turns one missed day into total abandonment—and shares how to set goals that actually stick.

We cover Strava's "Quitters Day" phenomenon (January 19th), why dry January might backfire, and why positive reinforcement beats self-punishment every time. Plus: Woody Guthrie's charmingly chaotic 1943 list of "New Year's Rulin's," including "wash teeth, if any" and "help win war / beat Fascism."
