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 […]

Altitude, Heat, and the Power Curve: Practical Physiology for Endurance Athletes

Two people in conversation at an outdoor table with rolling hills and cloudy sky behind them

Elite performance is built on a careful balance between stress and recovery, biology and behavior. This article translates practical lessons from applied sports science into usable guidance for endurance athletes and coaches. It covers how simulated altitude works, why erythropoiesis is not as simple as “more red blood cells = better,” how heat affects different […]
