    318. Our Surprising Take on Carb Loading, Why Even 10 Minutes Counts, Exogenous Lactate Supplementation, and Cross Training Science!

    We campaigned for the Nobel Prize in bodily functions before this great episode! A main topic was a new review study on cross training that found no difference between cross training and running interventions FOR RUNNING PERFORMANCE. That’s wild, and we use the result to zoom out to describe why we think most athletes should be doing some cross training. We also talked about a pair of studies on carb loading, and how the science debates are still uncertain. Even we are unsure as the biggest carb proponents in the world! And this one was full of great topics! Other topics: Megan’s breakthrough in side-short pees, arm cooling at the Tour de France, the strange world of lactate supplementation, multi-omic responses to training, building bone density, phobias, warm-ups, long runs, satisfaction meals, and science writing.  May your lives be like David’s legs: mostly smooth, with enough stubble to make it interesting.

    317. HISTORY at Western States 100! A Full Breakdown. Plus High Carb Study and Questions!

    The 2026 Western States 100 was astonishingly fast and uplifting! It was also astonishingly dramatic. This episode breaks it all down when it’s fresh in our minds. We talked the new course records and what it means to go for it in the modern era (and what it means to go for it in life). Other topics include the “death before DNF” mentality, brand battles, racing trends, and carbs in ultras. We brought some passion to this one, and we apologize if any conclusion went overboard (you can probably tell that David had some excessively hot takes). Plus there were lots of other cool topics! Other topics: Megan’s new piercing, a high-carb study showing dose-response with carbs and fatigue resistance, news from a pit toilet mishap, a proposal using cycling power profiles for detecting cheaters, the minimum volume to maintain adaptations, and a question on health anxiety. We use that anxiety question to zoom out and talk about a lot of big-picture topics. Western States always makes us existential, apparently.  Remember the big message: VROOM VROOM. It will make slightly more sense soon. We love you all! HUZZAH!

    316. Why Western States 100 Records Are Getting Smashed, Z1 v. Z2 Training, AI Coaching News, and Competitiveness v. Ego!

    It’s the best time of the year, and we brought that energy into this great episode! We started by bringing out our big predictions and hot takes for the Western States 100. The hottest take: everything about our understanding of endurance physiology is going to change on Saturday. We tell you why. We also talked about a new study asking a fascinating question: does the intensity of easy training matter for adaptations? The answer: not really, if overall stress is equalized. Our main conclusion is that no pace is too slow for aerobic development.  And this one was full of awesome topics! Other topics: switching heart rate monitors with a training partner, our complex thoughts on AI coaching, AI body scans, new data on trail supershoes crowning a possible champion, the perils of optimization based on studies, a cool study on human-wildlife conflict, competitiveness v. ego, burping in races, and a beautiful Listener Corner message.  Whenever you’re having a bad day, remember: there might be a thicc zebra waiting for you on the carousel of life.

    315. How Lower Carb Arguments Miss The Mark, Answering Bicarb Questions, Overload Weeks, and Heat Training!

    We developed the ultimate AM wake-up hack (which we tell you about in the intro) before this great episode! A main science topic was a new paper on how the temperature in an athlete’s training location influences race performance. It tells a story about heat training generally that everyone needs to pay attention to. And guess what? A new journal article makes yet another argument against higher carb approaches. David brings big rant energy and we talk about how the scope of conclusions from exercise science can sometimes be misinterpreted.  Plus, there were so many fun discussions! Other topics: Megan’s new documentary coming out on Thursday, what we’re seeing with bicarb use, overload training weeks, some cool science on Omega-3 supplementation, and questions on carbs in cycling, the backwards treadmill, big races, and more! To paraphrase our muse Jesse McCartney: we don’t want this episode to go to waste, we want you and your beautiful listens. We love you all! HUZZAH!

    314. Carbs and Bone Health, A Reproducibility Crisis in Training Science, Wild Data on Post-Exercise Ketones, and Trail Supershoe Data!

    We removed all the cutlery from our house before this great episode! The main science discussion was on a new study looking at reproducibility of adaptations in individual athletes. The relatively surprising finding is that there was no significant correlation in how the same athlete responds to the same intervention across time. We discuss what that means for training science. The word “holistic” is coming in hot. We also talked about a new study on post-exercise ketones, finding a 15% increase in natural EPO levels. Even knowing that, we aren’t recommending ketones to many athletes we coach. What’s going on? The disclaimers will blot out the sun. And this one was full of fun topics! Other topics: when good butter knives go bad, Tom Evans doing the coolest downhill training on the treadmill, new trail supershoe data, a study on carb intake and bone health, and how collagen may impact bone health for female athletes. Plus questions on breathing, uphill treadmill miles, breakups, programming workouts, coaching communication, and more. We love you all!

    313. Marathons v. Ultras, Fatigue Resistance Debates, Gene Editing Breakthrough, and Posture Impact on Blood Volume!

    We put some cinder blocks under the head of our bed (for science!) before this great episode. A weird study just came out finding that head-up sleeping may increase red blood cell totals. We talk about what it means and what it doesn’t mean. Excuse us while we launch a cinderblock start-up. We also discussed a breakthrough in gene editing for cholesterol, and what that could mean for the future. The world is going to be so different in 50 years! Maybe by then, David can use CRISPR to be able to pronounce science words.  And this one was full of fun topics! Other topics: our training log discussions, iron levels in athletes, breaking news on heat training from Unbound 200, a science debate on fatigue resistance terminology, and a study on glucose v. fructose. Plus, we answer questions on heat training in the car, clean sport for age group athletes, marathon v. ultra training, and health uncertainty. You’re going to learn a lot about what Megan would do for 40 grams of carbs. Totally normal stuff if you ask her! We love you all!

    312. How Blood Volume Impacts Performance and Adapts Fast, The Scary Potential of Lactate Supplementation, The True GOAT, and The Circle Pit!

    We basked in some amazing news before this great episode! The main topic was a breakdown of one of the most important elements of performance and health: blood volume.  Studies show that blood volume can seem to act as a synonym for fitness, with one finding that 6 weeks of training gains can be reversed with a phlebotomy that returns blood volume to baseline levels. Positive adaptations can happen in a few days, and it clearly matters for performance. If any other intervention worked like that, you’d assume everyone would be talking about it all the time. But blood volume is not discussed often! We pull back the curtain on the science. We also talked about a new review article on exogenous lactate supplementation. It might be a brave new world in the next 5 years, but right now there are more questions than answers. We speculate! And this one was full of cool topics! Other topics: the shockingly good news Megan has received in recent heart tests, our disdain for the Enhanced Games, recent age group doping news, the Satisfy Circle Pit, the true GOAT of endurance, running v. biking, uphill treadmill workouts, and lots more. Yes, David actually hit himself for a joke on this episode. Podcasts are definitely the medium for physical and visual comedy. We love you all!

    311. The Science Episode! How To Stop Cramps, Fat Oxidation Changes, Missing Link Heat Training, The Difficulty of Physiology Data, and More

    We talked about some of the strangest and coolest research topics in endurance sports for this episode! Basically, the science discussions went long, so we just ran with it. The main discussion was on how to stop cramps, laying out 10 theories. But put on your tin foil hats, because we think the cramping conspiracy runs deep. Our theory: cramping is connected to fatigue resistance is connected to all endurance performance, and thinking about cramp prevention might revolutionize all training theory even for athletes who never cramp. IT GOES DEEP! We also talked about a new missing link heat study, connecting altitude blood changes to long-term passive heat training. It was especially weird because the researchers were unsure of exactly why it happened. Those are the most fun study moments! Other topics: very short-term changes in fat max and fat oxidation (featuring the wildest figure we have seen in a long time), the difficulty of studies due to large error bars and small effect sizes, the crossover point in metabolic research, the incredible Dark Wizard documentary, and a question on relationships. For a clue about what was censored, here’s the hint: I caught mommy [bleeping] [bleepa blaus]. We love you all!
