| 4/29/26 |  Why You Should Always Be Training + Coach TJ's Canyons 100k Race Recap! | This week we welcome you behind the scenes of Microcosm Coaching with a quick introduction to Coach Zachary Russell, an athletic trainer and strength coach whose multisport background spans Ironman, triathlon, marathoning, and trail running. He shares what kinds of athletes light him up to coach and how his experience across disciplines shapes the way he builds plans.Then Zoë and TJ dig into TJ's recent Canyons Endurance Run 100K, which he completed roughly 80 minutes off his goal time after a brutal stretch of life context, including his dad's ongoing health and the loss of his uncle the night before the race. They talk about how Cliff and TJ restructured the build entirely, doing more base earlier and less intensity later, and yet Training Peaks read his fitness as identical to previous cycles. They get honest about caretaker stress, mental bandwidth, the choice to keep the door open to joy even when training feels heavy, and why the comparison trap between seasons can quietly steal everything.The bulk of the episode tackles a listener question from Delaney, who has noticed the same faces at every ultra and is wondering whether stringing races together actually counts as training. Zoë and TJ define training the way Microcosm uses it, intentional movement with an adaptive purpose, and reframe it as a continuum rather than a binary. They unpack the B race concept, the difference between racing it and running it, the lily pad effect of bouncing race to race without ever integrating what you learned, and the diminishing returns of using events as a substitute for consistency. They also offer a few honest questions to ask yourself, including whether you would still be putting in this volume if nothing were on the calendar, and what it means to build a higher floor in the interstitial periods most runners ignore.Have a question for the show?

| 4/22/26 |  5 Reasons Your Fitness Is Stuck (and How to Get Unstuck) | Why does your running fitness plateau, and what can you actually do about it? Zoë and TJ break down the five real reasons endurance athletes get stuck, a lack of training intentionality, under-recovery, chronic under-fueling, a mismatch between training and event demands, and failing to apply progressive overload across more than one lever. This episode also features a coach spotlight with James Nance, a Microcosm coach specializing in multi-sport athletes and RED-S recovery, TJ's mindset heading into race week at Canyons 100K, and a Reddit question on why your legs fall apart after your first 50K.New to Microcosm?

| 4/15/26 |  The Science of Periodization: How to Actually Structure Your Training Year | Most runners follow a training plan. Very few understand the architecture behind why it's built the way it's built, and that gap is exactly where progress stalls.This week, we break down the science of periodization: what it actually is, how to structure a full training year around it, and the most common mistakes that keep athletes stuck in the gray zone. We cover training intensity distribution (pyramidal vs. polarized vs. mixed), block versus concurrent periodization and what the research actually supports, the five phases of a well-built training year, and why your easy days are probably not easy enough. Zoë also shares what she's noticed firsthand after switching to a block-style approach in her own training, the good, the bad, and the PRs.Before the main topic, we run through a Hot or Not triple-header: Nomeo broccoli sprout shots (real mechanism, no peer-reviewed human data yet), the Apex Narwhal palm cooling device (the Stanford science is interesting, the application for runners is not), and pelvic floor PT, which gets a full endorsement for every runner, regardless of gender or whether you've ever been pregnant.New to Microcosm?

| 4/8/26 |  5 Signs You're Ready to Race (And 5 Signs You're Not) | Most runners ask one question before a race: did I finish my training plan? But fitness and race readiness are not the same thing — and in this episode, Zoë and TJ break down the physiological and psychological framework that actually tells you whether you're ready to toe the line.They start with the foundational model: fitness + freshness + specificity. Using the Banister fitness-fatigue model, they explain how both signals decay at different rates (fatigue's half-life is roughly 7–10 days; fitness is 40–45) — and why that gap is exactly where your race-day performance capacity lives.From there, they go sign by sign through five indicators you're ready — including aerobic decoupling and cardiac drift as readiness metrics, what glycogen supercompensation actually feels like during taper, why race-specific physiological systems (VO2max, lactate threshold, SGLT-1/GLUT-5 gut adaptation) can't be faked on race day, and how pre-race anxiety and pre-race arousal are the same physiological state with a different cognitive label.Then the five signs you're not: climbing out of a fatigue hole your neuroendocrine system is still broadcasting, missing race-specific work that willpower can't replace, running on a pain you've been rationalizing, under-fueling and under-sleeping your way to the start line, and the hardest conversation in coaching — when your goal and your fitness aren't in the same zip code.They also get into: Hot or Not on energy drinks at aid stations, AI-generated Spotify playlists vs. human curation, multi-day races and FKTs, and Prancercise (yes, really).Topics covered:The Banister fitness-fatigue model and why fitness and freshness decay at different ratesAerobic decoupling (Pa:Hr) and cardiac drift as race readiness signalsTraining Stress Balance (TSB): what the +10 to +25 range actually meansGlycogen supercompensation during taper — and why you should not get on a scaleVO2max, lactate threshold, and time-on-feet: the specificity gapGut training: SGLT-1 and GLUT-5 transporter adaptation, and why 12 weeks out is not too earlyPre-race arousal vs. anxiety — the Alison Wood Brooks reappraisal researchHPA axis dysregulation, HRV, and the neuroendocrine signals of a fatigue holeDOMS vs. injury-relevant pain — the checklist coaches actually useWIG, WAG, and WOG: cascading race goals and why rigid goals aren't ambitiousMore at microcosm-coaching.com.

| 4/1/26 |  UTMB Chianti Castles UTCC 120k Race Recap + Fueling Short Runs and Psychedelics for Running? | Zoë and TJ are back from Italy and kicking off April with a packed episode. First up: coach Kyle Jones: a masters athlete and ultra running specialist with a focus on helping athletes who are all in on the long game, whether that's accumulating volume safely or solving the full puzzle of race-day logistics that go far beyond training.Then it's Hot or Nots. On the docket: incline stretch boards for calf and Achilles work (the evidence is real, but eccentric loading beats passive stretching for most underlying issues), packaged Rice Krispie Treats as race fuel (the macros check out — 27 to 30 grams of carbs, glucose plus fructose, low fiber — but the chewability at mile 50 is another story), Ziploc bags in ice bandanas (hard pass: the evaporation is the whole point), hybrid athletes as a category (the jury is out, but the coaches aren't your girls if high rocks is your thing), run clubs (yes, with a firm caveat on effort), and microdosing during ultras (the research case for decriminalization is strong; the research case for running 100 miles on psilocybin is still pending).The listener Q this week tackles one of the most common rules in running: you don't need to fuel for efforts under 90 minutes. Zoë and TJ break down why that's only half the story. There are actually two separate mechanisms at play — the metabolic pathway most runners know, and a neurological pathway most don't. Receptors in the mouth and upper GI tract signal the brain the moment carbohydrates are detected, easing the protective fatigue response before a single calorie has been absorbed. This has been demonstrated even when athletes swish a carb solution and spit it out. For high-intensity efforts like a hard half marathon, the case for fueling is stronger than the 90-minute rule suggests — and the practical takeaways are in the episode.The back half is a full race debrief on Chianti. Zoë ran an hour faster than last year and still came in 13th. TJ walks through how to approach a post-race analysis when the headline result doesn't tell the full story — and how Zoë's coach surfaced a key data point she almost missed entirely: cardiac drift. In 2025, Zoë's cardiac drift was 9.54% over the course of the race. In 2026, it was negative 1.39%, meaning she was actually able to access higher heart rates at the end of the race — a direct signal of aerobic durability built by keeping easy days genuinely easy, week after week. The conversation covers what cardiac drift actually measures, why gray zone training works against this adaptation, and what the terrain-specific limiter was that explains the placement gap. | — | ||||||
| 3/17/26 | The Performance Trap: What Elite Male Athletes Get Wrong About Discipline, Leanness, and Control | If you've ever thought "I'm not dieting, I'm optimizing", this episode is for you.We're dropping this one from the Your Diet Sucks vault because we think it belongs in the feed of every endurance athlete. We brought in coach TJ David, former professional skier and elite endurance athlete, and Sean Van Horn, elite athlete, Kylee Van Horn's husband, and someone who spent six years not telling a single person he was struggling, because the way it shows up in men doesn't look like what we're trained to recognize.It looks like discipline. It looks like being serious about your sport. It looks like The Rock's morning routine and Chris Froome dropping weight before the Tour. From the outside, and often from the inside, it looks like exactly what you're supposed to be doing.That's the trap.We get into the data (it's stark,and most of it is probably still an undercount), the cultural pipeline from GI Joe to fitness influencers to the manosphere, why the diagnostic tools were literally designed for someone who is not you, and what coaches and training partners can actually do when they see it in someone they care about. Sean also shares his own story, which takes guts, and is worth your full attention.You don't have to identify with any particular label to get something out of this one. If you train hard, care about performance, and have ever used food or exercise as a way to feel in control of something, this conversation was made for you. | — | ||||||
| 3/11/26 |  5 Most Overhyped Ideas in Endurance Training (And What Actually Works) | Meet coach Kyle Jones, a master's athlete dedicated to helping other runners achieve their biggest goals, no matter their age. See more and book a free consultation call at microcosm-coaching.com.Every few months, a new training idea goes viral, and suddenly it's everywhere. Zone 2. Cycle syncing. Ketones. Heat suits. Ninety grams of carbs an hour. The science behind most of these things is real. That's not the problem. The problem is that real science is getting stripped of context, flattened into a hot take, and sold to athletes who haven't built the foundation that makes any of it matter.In this episode, Zoë and TJ break down five ideas that are genuinely overhyped, not because they don't work, but because the way they're being applied and marketed almost always skips the part where they actually become useful. They cover the five-zone model and why zone obsession can accidentally produce the worst possible training distribution, the booming female-specific training industry and what the 2025 research actually says about cycle syncing, performance supplements like creatine, sodium bicarb, and ketones and where the hierarchy breaks down, the ninety-gram carb protocol and why it's solving a problem most recreational athletes don't have, and heat training protocols and how fitness alone outperforms heat exposure for the vast majority of athletes.The through line across all five: marginal gains are real, but they sit on top of a foundation. And if the foundation isn't there, no intervention is going to save you. Sleep, consistent training, fueling the work, and getting your brain right, those are the levers worth pulling first. | — | ||||||
| 3/4/26 |  Should You Run Twice a Day? The Science Behind Running Doubles | Running twice a day sounds serious, but is it actually right for you? This week, Zoë and TJ dig into the full science of doubles: what they are, what they're definitively not, and how to know if you're actually a candidate. Plus, a round of listener-submitted Hot or Nots and a great question about why early morning runs feel so much harder.First up, meet Coach James Nance, a multi-sport specialist who coaches cyclists, runners, and skiers through big goals without burning them out. He's based in Fort Collins and has a knack for athletes navigating injury cycles, overtraining, and RED-S. If any of that sounds like your situation, reach out at microcosmcoaching@gmail.com.Then, a deep-dive Hot or Not round featuring listener submissions: inversion tables (the effects last minutes, not months), muscle scraping (the original theory has been pretty much debunked), CBD and THC cream (weak evidence, real anti-doping risk), and Superfeet insoles (a rare instance where the research actually delivers, prefab orthotics perform as well as custom at a fraction of the cost).Before the main topic, TJ answers a listener's question about why Zone 2 feels brutally hard at 5 a.m., and it turns out it's not just you. Core temperature, sleep inertia, cortisol, glycogen state, darkness, and cold all compound to inflate your RPE before you've even hit the first mile. There's real science here, and real solutions.Then: doubles. An elite running a morning threshold session and an afternoon shakeout is doing something fundamentally different than a recreational runner cramming two hard efforts into a day. Zoë and TJ break down the physiology of why doubles work when they work (hint: PGC-1α, mitochondrial biogenesis, and aerobic signaling), who's actually a candidate, the gray zone trap, the ego trap, and why energy availability is non-negotiable if you're going to add volume this way. Bottom line: doubles are a tool, not a trophy. | — | ||||||
| 2/25/26 |  What Good Running Coaching Actually Looks Like (And How to Find It) with Cliff Pittman, CTS Coaching Development Director | We brought in the person we trust with our own training. Cliff Pittman is the Director of Coaching at Carmichael Training Systems, which means he's essentially a coach of coaches, overseeing the education and development of CTS's entire coaching staff. He's also, full disclosure, our coach. So we wanted to have an honest conversation about what coaching actually is, what it isn't, and the massive gap between what athletes see and what goes on behind the scenes.Cliff walks us through the three pillars of good coaching: personal connection, evidence-based training, and data-informed decision making. We get into the invisible daily work that most athletes never see, why individualized coaching matters so much more than a static plan, and when a good coach should say "that's above my pay grade." We also dig into scope of practice, the uncomfortable gap between what athletes expect coaching to cost and what it actually costs, and how to find a coach who's the right fit for you, not just the most credentialed person on paper.Whether you're currently coached, thinking about it, or coaching athletes yourself, Cliff brings a perspective shaped by a decade in the military, executive coaching, and now leading one of the biggest coaching organizations in endurance sports.Plus, a quick introduction to Microcosm coach Zack Russell at the top of the show. | — | ||||||
| 2/18/26 |  Is Running 30 Ultras a Year Actually Destroying Your Body? The Science | Is your watch making you a worse runner? We dig into two powerful books — The Way of Excellence by Brad Stulberg and The Score by C. Thi Nguyen — to unpack how metrics, Strava segments, and training scores can quietly hijack your motivation and identity as an athlete.We also tackle a wild listener question: a 23-year-old running 30 hundred-milers a year. We break down the real physiology — rhabdomyolysis, acute kidney injury, endocrine suppression — and the psychology of the attention economy, dopamine loops, and identity fusion.Plus Hot or Nots on running onesies, ankle weights, and legs up the wall. And meet Microcosm coach Kristin Layne, who specializes in multi-sport coaching for busy athletes.Key topics: value capture, intrinsic vs. extrinsic motivation, the 4 phases of competence, running by feel vs. running by data, RPE, and defining success on your own terms.Books discussed:The Way of Excellence — Brad StulbergThe Score — C.

The process for preparing to go longer than you ever have is more similar across distances than you might think. TJ and Zoë break down the physiology, psychology, and practical strategies behind training for longer distances, from glycogen depletion and fat oxidation to the central governor theory and how to build your long run without getting hurt.Plus: Meet Microcosm coach Kristin Layne, and a new batch of Hot or Not — the Enhanced Games, face glitter, stair steppers, and smart shoes.Topics covered:Why your body enters a different metabolic reality after 90–120 minutesThe glycogen ceiling, fat oxidation, and mitochondrial densityWhy connective tissue adapts 6–12 months slower than your cardiovascular systemHow to build your long run gradually (and why it shouldn't exceed ~30% of weekly volume)Time-based training vs. mileage-based trainingThe central governor theory and training your brain to go furtherFueling for long efforts: 60–90g carbs/hourWhy back-to-back long runs are smarter than one mega-long runRPE guidelines for long runs (stay at 5–6)Strength training for durability at ultra distancesJoin Foothills: microcosm-coaching.com | Code: FOOTHILLS10Contact: microcosmcoaching@gmail.com | — | ||||||
| 2/4/26 |  7 Biggest Nutrition Mistakes Runners Make (And How to Fix Them) | Is fasted running sabotaging your performance? Are you accidentally under-eating on your hardest training days? This week, we break down the seven most common nutrition mistakes runners make, from calorie restriction at the wrong time to blindly copying elite protocols, and explain why the science says you probably need to eat more, not less.We cover why your gut issues might actually be a training problem, not a food problem. We talk about why "clean eating" is often just restriction in disguise. And we explain why doing what Kipchoge does probably isn't what you should be doing.Plus, we answer listener questions on accountability and whether high-carb fueling causes diabetes (spoiler: it doesn't). And Coach James Nance joins to talk about coaching multi-sport athletes, helping runners recover from overtraining, and his TrainingPeaks hot take that might surprise you.In this episode:Why restricting calories on training days backfiresThe truth about fasted running and morning workoutsHow to actually fix gut issues during exerciseWhy "clean eating" can become problematicWhat 90-120g of carbs per hour actually means for recreational runnersHow to evaluate nutrition advice and follow the moneyStudies and resources mentioned are linked below.Get involved: Join our Foothills coaching community—one-on-one coach access, twice-monthly roundtables, and a supportive crew of runners. $10/month with code FOOTHILLS10 at microcosm-coaching.com.Questions? microcosmcoaching@gmail.comREFERENCES:Burke, L.

| 1/28/26 |  6 Principles for Training Through Big Life Changes | How do you keep training when life gets stressful? Whether you're navigating a new job, new baby, a big move, or personal loss, your body processes all stress the same way—and that changes everything about how you should train.In this episode, we break down the science of stress and running performance, including how the HPA axis works, why your "stress bucket" has a finite capacity, and why the same workout that built fitness last year might dig a hole this year. We share six practical principles for training through life transitions without burning out or losing the fitness you've built.We also tackle Hot or Nots on splitting your runs (why two 4-milers isn't the same as one 8-miler) and running in extreme cold (when to embrace the treadmill). Plus, we debunk that viral Noakes study claiming you only need 10 grams of carbs per hour—spoiler: it's a cherry-picked narrative review from low-carb advocates with ketone patents.What you'll learn:– How cortisol and the HPA axis affect your training and recovery– The "stress bucket" model and why your capacity changes during transitions– Why RPE increases at the same pace when life stress is high– How to flip your training hierarchy so life leads and running follows– The detraining timeline (it's slower than you think)– How to set "conditions of enoughness" for your current season– Why frequency beats volume during chaotic periodsAlso in this episode: Meet Coach James Nance, who specializes in multi-sport athletes, injury cycles, and RED-S recovery.microcosmcoaching@gmail.com | microcosm-coaching.com | Join our Foothills community for $10/month | — | ||||||
| 1/21/26 |  How to Return to Running After Time Off , Plus: Burrito League and Plyometrics! | Taking time off from running, whether from injury, illness, or life—doesn't have to derail your progress. In this episode, we break down the actual physiology of detraining and give you a science-backed framework for returning smarter, not just faster.We cover what happens to your body during time off (spoiler: it's not as catastrophic as your brain tells you), why connective tissue is the real limiting factor in comebacks, and how to use RPE and walk-run protocols to rebuild safely. Plus, we get into the mental game of accepting where you are versus where you were.Also in this episode: We weigh in on Burrito League (not hot), Strava's AI workouts (also not hot), and whether plyometrics belong in your training. And Zoë asks TJ a question from her own training log about whether running faster on good days is actually worth it. | — | ||||||
| 1/14/26 |  When Cross-Training Helps Runners (And When to Just Run More) | 📧 microcosmcoaching@gmail.com🌐 microcosm-coaching.com💬 Foothills Community: $10/month (code FOOTHILLS10)Does cross-training actually help runners, or is it just a distraction from the main thing? We break down the research on what transfers to running performance and what doesn't, covering AlterGs, curved treadmills, ellipticals, cycling, swimming, yoga, and Pilates.The key finding: VO2 max transfers between modalities, but running economy does not. Runners who replaced all running with elliptical for five weeks maintained their aerobic engine but got slower. We dig into who actually needs cross-training (masters athletes, injury-prone runners, those at their volume ceiling) versus who should just run more.Plus: Hot or Not rapid fire on cross-training equipment, including the truth about weighted vest walking and why curved treadmills make you work 30% harder for worse results. | — | ||||||

Welcome to our first episode of 2026.We kick things off with our Athens Big Fork Trail Marathon race recap—Zoe ran an 8-minute PR after 4 years of training (that's 30 miles per second of improvement), while TJ ran his worst time ever and learned some valuable lessons about mental performance and showing up when things don't go your way.Then we answer a listener question: Does shoe cushioning actually matter for injury prevention? The 2024 research from Malisoo et al. might surprise you—it's not about how soft your shoes are, it's about something else entirely.Our main topic: 5 signs your easy runs aren't easy enough. This is the single most common mistake we see as coaches, and fixing it might be the highest-leverage change you can make to your training. We break down the physiology of why slow running makes you faster, what the 80/20 research actually says (including a 2025 meta-analysis), and give you 5 concrete signs to watch for.In this episode:• Athens Big Fork Trail Marathon race recap• The math behind 4 years of training for an 8-minute PR• How to compete hard even when having a bad day• Shoe cushioning research: perception vs. mechanics• The physiology of aerobic vs. glycolytic training• What 80/20 polarized training really means• 5 signs your easy runs aren't easy enough• How Kipchoge's easy pace compares to recreational runnersStudies referenced:• Rosenblatt et al. 2025 (Sports Medicine) - Polarized training meta-analysis• Jong et al. 2025 (Applied Sciences) - Sleep and injury risk in runners• Malisoo et al. 2024 (European Journal of Sports Science) - Shoe cushioning perceptionConnect with us:Email: microcosmcoaching@gmail.comWebsite: microcosm-coaching.comJoin Foothills group coaching ($10/month with code FOOTHILLS10) | — | ||||||
| 12/31/25 |  5 Off-Season Habits That Will Make You a Stronger Runner in 2026 | Your off-season choices today determine your race day results tomorrow.Most runners get the transition season completely wrong—they either hammer through on their way to burnout or disappear entirely and spend January rebuilding from scratch. In this episode, we break down what actually works for year-over-year improvement.We cover why taking zero time off after race season is a recipe for injury and plateau, the science of post-race recovery (CNS fatigue, hormonal reset, glycogen restoration), and why detraining fears are almost always overblown. We play Hot or Not with common off-season approaches so you know what to keep and what to ditch, discuss frequency goals vs. volume goals and why the switch changes everything, and talk about building accountability systems that don't rely on motivation.The bottom line: rest is part of training—make this a core belief in 2026. You can cut volume in half for 4-6 weeks and only lose 5-10% fitness. Simpler plans are more likely to be followed. And your January determines your July.Before spring hits, take 2-4 weeks of intentional rest after your last A-race, complete a full season assessment to identify 2-3 specific pain points, set frequency goals for transition season, build at least one accountability system into your training, and schedule monthly low-key events to stay engaged.Connect with us:Email: microcosm.coaching@gmail.comWebsite: microcosm-coaching.com | — | ||||||

| 11/25/25 |  RED-S Explained: Why Underfueling Hurts Your Performance More Than You Think | Training harder but not getting faster? Dealing with recurring injuries? The problem might be your fuel.Before Thanksgiving, I'm sharing an episode from Your Diet Sucks about RED-S, the energy mismatch that's quietly destroying athletic performance and causing injury after injury.When you chronically undereat for your training load, your body can't adapt. You're doing the work, but not getting the gains. Studies show athletes with RED-S are 4.5x more likely to get bone injuries and miss significantly more training time.Signs You're Underfueling:Training harder but getting slowerStress fractures or injuries that won't healConstantly exhausted despite rest daysLost period (or loss of morning erections in men)Frequent colds and illnessYou can't out-train a calorie deficit. Adequate fueling is how you honor your training. Going into the holidays: eat the food, recover hard, and come back stronger.In this episode: What RED-S is, how it shows up in male athletes (often overlooked), why it prevents adaptation, and how to fuel for actual performance gains, not just more miles.Listen before your holiday meals. Food is fuel. Recovery is where you get faster. | — | ||||||
