Average and Maximum Heart Rate
Observed session intensity interpreted relative to movement mode, pace, elevation, altitude, duration, terrain, and prior load.
Field-derived signals interpreted under movement, altitude, terrain, metabolic context, sleep, recovery, and time—not isolated numbers removed from the world that produced them.
A number becomes useful when the system understands how it was measured, what surrounded it, what it cannot establish, and whether later observations support or contradict the interpretation.
Direct signals are recorded by wearables or field instruments. They remain estimates and become meaningful only with route, environment, timing, measurement quality, and recovery context.
Observed session intensity interpreted relative to movement mode, pace, elevation, altitude, duration, terrain, and prior load.
Longitudinal autonomic context. Neither value independently certifies readiness, recovery, or adaptation.
Overnight context that may be relevant after altitude, travel, poor sleep, illness, or unusual strain.
Garmin estimates describing the character of an effort—not laboratory measurements of adaptation.
A wearable estimate interpreted alongside duration, terrain, altitude, mechanics, symptoms, and subsequent return.
A directional ketone-production signal. It does not directly measure blood ketones, fat oxidation, autophagy, or clinical metabolic status.
Sleep score, duration, deep sleep, REM, awake time, fragmentation, overnight stress, HRV, and resting heart rate.
Terrain, altitude, weather, temperature, wind, surface, carried load, fueling, hydration, and technical demand.
Fatigue, soreness, cognition, pain, illness, perceived exertion, and practical field judgment remain part of the record.
Distance, duration, gain, heart rate, load, altitude, environment, mechanics, metabolic context, and symptoms.
Sleep, HRV, resting heart rate, stress, soreness, fatigue, symptoms, and time—without converting one delta into proof.
The next relevant effort can support, refine, or contradict an interpretation while remaining observational.
| Earlier biomarker story | Current evidence | Treatment |
|---|---|---|
| Wheeler was the first positive-drift hike and a fatigue-reveal effort | Five positive-drift hikes preceded Wheeler; drift and pre-hike HRV correlated at r = +0.03 | Fatigue-reveal claim withdrawn |
| Pre-to-post HRV delta measured recovery cost | The delta correlated with its starting value at r = −0.738 | Derived metric retired |
| Pikes demonstrated recovery failure before performance | Low absolute HRV and difficult sleep context remain observations; the retired delta does not establish failure | Causal claim withdrawn |
| Negative drift independently certified cardiac efficiency | Whole-route drift is route-, pace-, terrain-, altitude-, temperature-, and recording-dependent | Retained as directional context |
The final 16 hikes also showed lower mean exercise load—65.8 versus 131.0—despite greater average duration and elevation gain.
Median −0.96%. Useful as a direction of heart-rate change, not a total-cost or readiness score.
Recorded on San Jacinto and Mount Elbert. The values remain descriptive metabolic context, not an autophagy measurement.
It does not prove that the dose was optimal, fully absorbed, or immediately repeatable.
Mount Baldy, Mount Wilson, San Jacinto, San Gorgonio, Baden-Powell, and the Icehouse Canyon network provide recurring environments for comparison across seasons, metabolic states, protocols, weather, and recovery histories.
Route continuity reduces some noise, but pace, terrain, weather, stops, altitude exposure, recording structure, and human state remain active. The strongest interpretations come from the full distribution rather than a single dramatic session.
