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.
