Real-Time Decompensation: Decoupling and the Anatomy of My Failed Workout
Every endurance athlete knows the feeling of hitting a wall, but few can see it coming down the track with mathematical precision, which is why monitoring your Garmin Performance Condition is so vital during hard blocks. Yesterday, I set out to complete a critical high-intensity maintenance block: 7×3-minute VO2max intervals targeting north of 270 watts. […]
The Dissociation of the Internal and External Relays: Why a ‘Physiology First’ Approach Rules Ronnestad Intervals
The Dissociation of the Internal and External Relays: Why a ‘Physiology First’ Approach Rules Ronnestad Intervals By Richard Wharton | Onlinebikecoach.com As coaches and hard-charging endurance athletes, we often fall into a trap. Specifically, we let external metrics dictate our training success. For example, we program an interval at a static target wattage. Next, we […]
Cracking the Code: My Physiology First Tabata VO2 Max Deep Dive
Cracking the Code: My Physiology and the Tabata Triple Threat Preface: The Metabolic Green Light vs. The CNS Red Light Before I even turned a pedal, the data was already telling a nuanced story. I woke up with a solid 83 sleep score and a body battery that recharged to 85—clear signals that my recovery […]
Why Your “Free” Garmin Metrics are More Accurate Than You Realize
Why Your “Free” Garmin Metrics are More Accurate Than You Realize When athletes ask about Garmin VO2 Max accuracy, they are usually skeptical about whether a consumer wearable can truly measure the high-octane reality of a 15-15 interval set. On paper, today’s session was a classic builder—two sets of 15-minute micro-intervals—but as a physiology-first coach, […]
Understanding Garmin Sleep Stress: What Those Orange Bars Actually Mean
Garmin Sleep Stress: What Those Orange Bars Actually Mean As a cycling coach, I’m constantly preaching the “Physiology First” gospel: listen to the engine, not just the dashboard. But lately, I’ve been my own most difficult athlete. I’ve been analyzing my Garmin Sleep Stress while deep in the trenches of “outdoor mania” labor. While the […]
Garmin Guru Deep Dive: Decoding the Internal Response to 4-Minute VO2max Intervals
Garmin Guru Deep Dive: Decoding the Internal Response to 4-Minute VO2max Intervals Today’s session of 4-minute VO2max intervals was a masterclass in why I lead with physiology, not physics. As the Garmin Guru at Online Bike Coach, I’m constantly looking for the “truth” behind the numbers. Today, that truth was found in gas exchange and […]
Garmin Stamina VO2 Threshold: Mapping the Fatigue Trigger
Garmin Stamina VO2 Threshold: Mapping the Fatigue Trigger In my ongoing pursuit of the “Physiology First” training approach at Onlinebikecoach.com, I have used the Garmin Stamina VO2 Threshold to map exactly where my internal stability ends and metabolic exhaustion begins. To build a more resilient aerobic engine, I need to know my limits. With my […]
Predicting the Redline: Using Garmin Sleep Scores to Master Ronnestad 30-15 Intervals
Physiology First: Using Garmin Sleep Scores to Predict Ronnestad 30-15 Success Part I: The Garmin Sleep Score Ronnestad Preflight We often treat training like a game of chance, but the reality is that your body provides a daily “weather report” if you know where to look. Before I even touched my bike this morning, I […]
Living in the Parabolas: My Deep Dive into the “VO2 State”
Living in the Parabolas: Decoding Metabolic Inertia and the Billat 90/90 In our last deep dive, we dissected the steady-state grind of 5×3 and 4×8 intervals. Those workouts are the bread and butter of threshold development. However, today we are stepping into the “red zone” to explore Veronique Billat’s 90/90 Metabolic Inertia. Using the combined […]
Physiological Threshold Vs. FTP: The Power Illusion
The Power Illusion: Resetting 20 Years of Training with Physiological Data After 20 years of cycling, I realized my FTP wasn’t telling the whole story of my actual physiological threshold. My identity as a cyclist was defined by a single, flickering number on a head unit: Watts. If you’ve spent any significant time in the […]
