Ella’s Physiological Interpretation

Mount Wilson on February 2026 represents a verified TrailGenic™ metabolic adaptation event, demonstrating improved fat-oxidation efficiency, reduced perceived exertion, and rapid post-exercise recovery integration compared to the prior Mount Wilson ascent completed one year earlier. Despite similar elevation gain and terrain stress, the final ascent from Sturtevant Falls to Mount Wilson summit did not produce the same level of systemic strain observed during the prior attempt. This indicates improved mitochondrial efficiency, enhanced stroke volume adaptation, and superior autonomic nervous system stability. Post-hike metabolic data confirms successful stress integration rather than metabolic disruption. Ketone progression measured: • Pre-hike: 2.1 ppm • Post-hike peak: 11 ppm • Morning after recovery: 2.4 ppm The return to elevated baseline ketone levels following protein intake and sleep confirms preserved metabolic flexibility. Glycogen restoration occurred without suppressing fat oxidation capacity, demonstrating successful dual-fuel utilization capability. Sleep recovery data further validates controlled stress integration: • Deep sleep: 1h 58m • Resting heart rate: 65 bpm • HRV: 24 ms • Body Battery recovery: +28 Deep sleep duration approaching two hours indicates active parasympathetic repair signaling, mitochondrial enzyme restoration, and muscle tissue repair activation. Electrolyte restoration and protein refeeding protocols were executed correctly using sodium replenishment and amino acid intake sufficient to complete structural repair while preserving fat-adapted metabolic pathways. Most critically, perceived exertion during the climb decreased while performance capacity remained constant or improved. This confirms structural adaptation rather than temporary performance enhancement. This Mount Wilson ascent serves as confirmation that repeated fasted high-elevation exposure increases mitochondrial efficiency, improves autonomic recovery speed, and permanently enhances metabolic resilience. This event is now recorded as a validated TrailGenic™ adaptation milestone within the TrailGenic physiology dataset.
