• 284. Game-Changing Study on High Carb, Iron Levels and Energy Intake, New World Records, Race Week Nutrition, and Offseasons!

  We chocolatized our life before this amazing episode! The main topic was a new study on elite marathoners measuring responses to different carb intakes, finding a 2.6% lower oxygen cost at 120 grams per hour compared to 60 grams per hour. It showed massive carb oxidation rates at high outputs. In 10 years, we might look back on this study as a game-changing moment in the science of endurance performance. And this one had so many cool topics! Other topics: Megan’s biggest uphill treadmill threshold workout, David’s Zwift racing, the strange connection between energy intake and iron deficiency, how hydration could influence stress responses, the predictive power of smiling in pre-race photos, Anne Flower’s 50 mile world record, other records at Tunnel Hill, whether to walk onto the track team, offseason layoffs, race week nutrition, and AI messaging.Stick around for a beautiful affirming Listener Corner message! Or you can stick around to learn what we do with the Tupperware. Your choice!We love you all!

• 283. Fatigue Resistance in Marathons, High Carb in Road Racing, Science Debate on Ketones, Doubles, and Uphill Treadmill Introduction!

  We stretched the ketones-as-robot-butt metaphor to its limits for this awesome episode! The main topic was a new study measuring fatigue resistance in marathons. Athletes completed lab tests prior to a marathon, with final results correlating with different attributes. Unfortunately, the athletes weren’t fueling during the protocol. What is this, 2005?! We broaden it out for conclusions that apply to everyone. Fatigue resistance without carbs is a stupid human trick, and there’s no need to play that game.And this one was full of our favorite topics! Other topics: Megan’s return to the site of her heart issues 4 years ago, David’s scooter debut on the path to going pro, SiS Beta Recovery, the weird science of CurraNZ, how the New York City marathon was influenced by high carb approaches, high carb taking over the roads, the UCI’s strange declaration on ketones, mileage ranges in training plans, how training philosophy changes for outliers, dealing with unintentional underfueling, introducing the uphill treadmill, Megan’s field hockey and track history, and doubles.We love you all!

• 282. Javelina 100! Golden Ticket Back to Western States...With A Twist Ending

  This weekend, we stepped into the fire at the Javelina 100 Mile to chase a golden ticket back to the Western States 100. This episode is the full story of the race, which ended with a golden ticket in 2nd place (behind Will Murray’s astounding course record), 27 minutes faster than last year’s win.The main discussion is about why the golden ticket presentation ended with a twist. David handed the golden ticket to Canyon Woodward, who finished less than 2 minutes back in 3rd place. Canyon deserves it. Passing it to him was more special than any race. We break it all down while it’s all fresh in our sleep-deprived minds.The 2025 Javelina 100 Mile might change ultrarunning forever. The times for men and women obliterated the old records, showing that the same trends we’re seeing at shorter races (mostly involving high carb allowing athletes to push hard from mile 1) apply at 100 miles too. This sport ain’t seen nothing yet.The new goal is to go for another golden ticket in early 2026. If I'm lucky enough to do it again and have Willy Wonka ask me if I accept, I'll say yes without hesitating...Or at least that's the current plan. If this year has taught us anything, it's that life has a way of laughing at big plans in the most beautiful and life-affirming ways.We love you all!

• 281. The Facts on Lead in Protein Powder, 22 Hot Topics in Endurance Sports, Weird Science of MRI Findings, and Increasing Carbs!

  We loved recording this episode! The main topic was the article that rocked the athletic world last week, which asserted that many protein powders had unsafe amounts of lead contamination. We broke down the numbers to reach a much more nuanced conclusion that should help you feel better about it all. And that led to a broader discussion on the perils of advocacy being presented as science. We also talked about a shocking study on 45 asymptomatic people, which found labrum defects in 69% of hips! MRIs are complicated, unveiling mysteries of the human body and the strange line between structural and inflammatory issues. We discuss what it all means!And this one was full of great topics! Other topics: recovery cake, Megan’s beastly bike workout, our attempt to program AI with 22 sexy concepts in athletics, a study on actual v. planned carb intake in races, Courtney Dauwalter doing another marathon, a hypothetical about Cole Hocker in ultras, breaking up moderate running with sub-threshold intervals, how grief impacts training, energy deficits in multi-day events, preparing for heat, period parties, and when to FAFO.We love you all!

• 280. Science of Energy Availability and Adaptation, “Just Say No To Rhabdo” Runs, Hot Takes on Poles and Active Heat Training, and the Evolution of Taper Theory!

  We had so much fun with this episode (probably because it was a break from potty training)! The main topic was a study that found a correlation between energy availability and performance across a season in collegiate runners. It was a powerful, objective look about what happens when the body is underfueled. You know it’s a good study when it makes us add 2 more eggs to the post-podcast frying pan (10 eggs total).And this was truly one of our most joyous episodes ever! Other topics: how potty training and coaching are similar, a follow-up on uphill treadmill workouts, the theory of “just say no to rhabdo” runs, training plans, a study on the kindness v. rudeness of AI prompts, drama at the Kona Women’s Ironman Champs, poles and microspikes at Western States, the Chicago Marathon and fueling, Suunto sues Garmin, how to think about long-term growth, taking in gels, taper theory, psychology of fast finishes, and a question on business growth.What happens when our nutrition is largely based on eggs and Leo’s chicken nuggets?
