The Power Illusion: Why Your Suspension Setup and HRV Dictate Real Speed

Short mountain bike stem upgrade for modern trail geometry used in physiology-first cycling training cockpit optimization.

Chasing Ghosts on Peavine: The Ecology of Speed By Coach Richard Wharton • May 27, 2026 Heading out from the Peavine Mountain Hoge Road Trailhead to collect raw biometric and suspension telemetry across the Halo Loop. Part 1: Physiology-First Cycling Training, the Weight, and the Climb Metrics It has been months since I last pointed […]

The Autonomic Pivot: When Less Training Volume Equals Deeper Recovery By Coach Richard Wharton, OBC | Published: May 25, 2026 Tracking my **Garmin HRV Stress** over the last few months has revealed a fascinating tug-of-war within my autonomic nervous system. Specifically, it shows exactly how shifting training workloads register on the body. Looking back at […]

Cracking the Code: My Physiology First Tabata VO2 Max Deep Dive

A comparison graph showing cumulative average power decay over three Tabata sets, highlighting higher initial intensity in Set 1 and more stabilized power in Sets 2 and 3.

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 […]

The Anatomy of a Good Ride; Physiology, Recovery, and the Portola Block

Cycling coach Richard Wharton on his bike in Portola, CA, after a breakthrough ride validating his Physiology First training methodology.

The Anatomy of a Good Ride: Physiology, Recovery, and the Portola Block I’ve always said that success on the bike isn’t a roll of the dice; it’s a deliberate convergence of external work and internal readiness. This week, I conducted a deep cycling physiology analysis of the Portola block to prove how disciplined recovery yields […]

Stamina, Speed, Strength, and Skill – 4 Spokes With a Hub called “Consistency”.

A conceptual bicycle wheel graphic showcasing the four pillars of Online Bike Coaching. A tri-spoke carbon fiber wheel features keywords printed on its blades: STAMINA, SPEED, and SKILL. At the central hub centerpiece, the word CONSISTENCY is printed twice. The full Online Bike Coach logo, as seen in image_20.png, is visible in the background.

Cycling Stamina and Strength: The S4 Framework Building elite cycling stamina and strength is the foundation of the S4 performance framework used by high-performance athletes.In the world of professional cycling, we often get distracted by the latest gear or chasing the highest wattage. But at its core, your performance is a wheel supported by four […]

The Garmin Daily Double Dip: A Stamina and Potential Deep Dive

The Garmin Daily Double Dip: A Stamina and Potential Deep Dive Coach Wharton – May 7, 2026 Understanding Garmin Stamina metrics like Actual Stamina and Stamina Potential has fundamentally changed the way we analyze real-time capacity and athletic recovery. While Potential represents your total “fuel tank” for the entire ride, Actual Stamina reflects what you […]

Rocky Terrain Suspension Efficiency: The Open vs. Locked Debate

Peavine Singletrack is fun, challenging, and easily accessible.

May 7, 2026 Rocky Terrain Suspension Efficiency: The Open vs. Locked Debate; A Peavine Challenge In November 2025, I conducted a “Physiology First” experiment on Reno’s Peavine Mountain to analyze rocky terrain suspension efficiency. This ride has since become the archetype and benchmark for my 2026 training season. The mission was simple: Two laps on […]

Why Your “Free” Garmin Metrics are More Accurate Than You Realize

Garmin Edge post-ride analysis showing Aerobic Training Effect of 5.0 and 72-hour recovery time.

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, […]

The Half-Glass Difference: How Alcohol Sabotages Your Garmin Recovery

A glass of red wine on a dinner table at an upscale restaurant, representing the setting for a physiological case study on recovery.

When analyzing Garmin sleep recovery, alcohol is often the “X-factor” that derails even the most disciplined athlete. We’ve all heard it before: “It was just a couple of glasses of wine.” But as a coach who lives by the mantra Physiology is King, I’m less interested in what the menu says and more interested in […]

Understanding Garmin Sleep Stress: What Those Orange Bars Actually Mean

Garmin Sleep Metrics screen showing 51 restless moments, 55 bpm RHR, and a low SpO2 dip of 83%.

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 […]
