The MicroCast

Coaching yourself? These are the five mistakes we see self-coached runners make most, and they're easier to fall into than you'd think. TJ and Zoë start with a listener question about the best time of day to train. Physiology gives late afternoon a small edge as core temperature and muscle readiness peak, but the real answer is whatever time lets you train consistently. They also cover running in the dark, why one missed workout doesn't matter, and whether evening runs wreck your sleep.Then the list. First, copying the wrong model, including what the HERITAGE family study found when hundreds of people did the identical training program and got wildly different results. Second, the Franken-plan, where a podcast workout, a YouTube session, and a group track night get stitched together with nothing connecting them. Third, training your strengths instead of your limiters, and how to periodize hills, speed, and technical downhills months out from your goal race. Fourth, the planning fallacy, and the research on why we underestimate how long everything takes, even compared to our own worst-case guesses. Fifth, making big training decisions in the wrong emotional state, from post-DNF race sign-ups to the dangers of watching a Billy Yang film on a full stomach.Plus, meet Microcosm coach Skylar, who works with road runners from the mile to the marathon.LinksFoothills community ($10/month, coach calls + Slack community), code FOOTHILLS10: https://microcosm-coaching.comWork with a Microcosm coach, including Coach Skylar: https://microcosm-coaching.comSend us your questions and Hot or Nots: [email protected]

Lactic acid, static stretching, stability shoes, heel striking, 180 cadence, and icing everything: some running advice has not held up. Coaches Zoë Rom and TJ David cover six common myths, what the research actually shows, and why some of these ideas have stuck around for so long. Zoë also apologizes to everyone she sold motion-control shoes to in Northwest Arkansas.Also in this episode:A listener asks why they feel wired and can't sleep after long runs. We cover what's going on in the nervous system, the caffeine you might be missing, and when this becomes a red flag.TJ gives an update on his health: he's been diagnosed with sarcoidosis after being misdiagnosed with HAPE at Leadville.Zoë recaps Mammoth Trailfest and shares a first look at next year's race plans.Resources mentionedCochrane Review (2022): running shoes for preventing lower limb injuriesPEACE & LOVE framework for soft tissue injuries (Dubois & Esculier, BJSM)Coaching: microcosm-coaching.com | Email: [email protected] and review wherever you listen.

Ready for your next ultra distance? Maybe. In this episode, we tackle the question of when to move up from the 50K to the 50 mile, 100K, 100 mile, and beyond, and why the "ladder" framing might be steering you wrong. Distance alone doesn't say much about what a race demands. A mountainous 50K can ask more of you than a runnable 50 miler, so we talk about how to size up a race by duration, terrain, and your own capacity.We start with a listener question: should you practice run-walking during ultra training, especially on tired legs in high-volume weeks? We explain why power hiking is a race skill, why fixed run-walk ratios work well in training but poorly in races, and why extra walking can be stress without much stimulus.From there, we cover how to identify your real weaknesses. That means separating a bad day from a pattern, finding root causes instead of symptoms, and deciding which limiters to address first. Spoiler: it's often fueling and hydration. We share practical approaches for improving speed, climbing, descending, durability, and your gut. We finish with the signs you're ready to move up, what does and doesn't change in training as races get longer, the special demands of 200 milers, and when it's better to wait.Plus, meet Microcosm coach Kylee Van Horn: nearly 20 years of coaching across road, track, and trail, a registered dietitian's lens on fueling, and a hot take about why you can't cross-train your way to a 100 miler.In this episode:Kylee Van Horn coach spotlightListener question: should you practice run-walking?Power hiking vs. walking, and why fixed ratios fail on race day"Stress, not stimulus": the hidden cost of extra walking volumeWhy the ultra distance "ladder" is a mythHow to find your weaknesses and root causesPrioritizing limiters: low-hanging fruit firstTraining for speed, climbing, descending, durability, and GI toleranceSigns you're ready to move up in distanceWhy 50K and 100 mile training look more similar than you thinkWhat makes 200 milers differentWhen not to move up, and the six-year testWant to work with Kylee or another Microcosm coach?

Zoë's article on Ability vs. AmbitionYDS Episode on "Racing Weight"There's always a gap between where you are as an athlete and where you want to be. Zoë wrote about it for UltraSignup , "Closing the Gap Between Ability and Ambition", and this week TJ reads it back to her, days before she lines up at Run Rabbit Run 100 for the third time. They dig into Ira Glass's idea of "the gap," why admitting you want to be great feels so vulnerable, what "spiritual durability" actually means in a training context, and why the most successful athletes usually aren't the most talented — they're the ones willing to sit in that discomfort long enough to close it.From there: why repeat a race you've already done well twice, why you technically can't (same course, different athlete, different river), how Zoë structures a year around two big hundreds using a rule of thirds, and how she's managing the comparison trap and her mental diet heading into a deeper field than she's ever raced.Then a listener question that comes up constantly: "I'm training more than ever and I've gained weight instead of losing it. Is that normal?" Yes — and here's what the scale is actually measuring: glycogen and the water it binds, inflammation from tissue repair, blood volume, food in transit. Plus what the research really says about body weight and injury risk, and when weight change is worth a conversation with a doctor.

How many miles a week do you need to run to get better? It's the question coaches hear most, and the annoying answer is: enough to create an adaptation, not so much that you can't absorb it. The body doesn't experience a mileage total. A mile on a 14er and a mile on a track are completely different stresses, which is why time at effort is a better way to think about volume than distance.TJ and Zoë break volume into four levers. How much: the difference between the minimum effective dose, the optimal dose, and the maximum recoverable dose, and why most runners should be asking about the middle one. How often: what 3, 4, 5, 6, and 7 days a week actually get you, and why frequency is the most overlooked tool for newer runners. How long: why 15 + 5 is not a 20-mile long run, and why the cost of a run doesn't rise in a straight line. And where: easy/hard distribution, the weekend-warrior trap, and why back-to-back long runs are a tool rather than an organizing principle. It all starts from the same place — the week you can actually repeat, found in your TrainingPeaks history, not the week you're proudest of.First, TJ has an answer for what happened at Leadville. Then: a listener question about Nordic skiing all winter and protecting running fitness for a spring 50K, and Hot or Not on mocktails, aid station hydration mixes, and Tiger Balm.Questions for a future episode: [email protected] and community: https://microcosm-coaching.com
