First 19 versus final 19 hikes. The later half occurred in warmer conditions and reached higher average peak elevation.
A longitudinal N-of-1 field record documenting observed performance and physiological context across Walking, Rucking, Running, and Hiking.
Sessions are measured under real load, terrain, altitude, heat, cold, wind, and long-duration stress. Direct measurements remain separate from interpretation; source columns govern, and full-record patterns outrank individual session stories.
The fixed one-year audit contains 93 sessions: 22 walks, 16 rucks, 17 runs, and 38 hikes. The live record now extends to 101 sessions: 24 walking, 18 rucking, 19 running, and 40 hiking. Foundation modalities remain controlled comparisons; Hiking carries the environmental model. The live hiking layer totals 430.66 miles, 164,610 feet of elevation gain, and 13,515.4 elapsed minutes.
First 19 versus final 19 hikes. The later half occurred in warmer conditions and reached higher average peak elevation.
First 19 versus final 19 hikes. Garmin load is a device estimate; the heart-rate direction is the primary finding.
| Earlier interpretation | Corrected record | Status |
|---|---|---|
| 29 of 32 hikes had negative drift; median −0.74% | 32 negative and 6 positive; median −1.0% | Superseded |
| Wheeler was the first positive-drift hike and revealed fatigue | Five positive-drift hikes preceded Wheeler; drift and pre-hike HRV correlated at r = +0.03 | Hypothesis withdrawn |
| Pre-to-post HRV change measured recovery cost and adaptation | Pre- and post-hike HRV correlated at r = +0.09; the delta correlated with its starting value at r = −0.738 | Metric retired |
| The Western Block revealed an Engine–Governor divergence | The founding HRV-delta comparisons were dominated by starting values and regression toward the post-hike mean | Dataset claim withdrawn |
Earlier session narratives remain part of the historical record, but the current one-year audit controls wherever those narratives conflict with corrected source columns.
Median −1.0%. A descriptive whole-route direction—not a validated efficiency, fatigue, fitness, or readiness score.
Median breath acetone rose from 2.2 to 7.3 ppm; the observed high was 22 ppm. It is not blood ketones, fat-oxidation rate, autophagic flux, or clinical metabolic status.
Across 34 pre-, post-, and day-2 triplets, day-2 HRV exceeded immediate post-hike HRV in 30 cases. This describes recovery timing; it is not a validated readiness score.
Elbert, Manitou, Pikes, and Wheeler document 37.63 miles, 15,867 feet of gain, and 24.2 hours under compressed travel and altitude conditions. They do not establish a distinct recovery governor, physiological ceiling, or Wheeler fatigue marker.
| Effort | Field facts | Observed signal | Boundary |
|---|---|---|---|
| Mount Elbert | 11.02 mi · 5,361 ft · 473 min · 14,497 ft | 127 bpm · −1.30% · 22 ppm | Highest recorded elevation and tied-high acetone; not a proven recoverable ceiling |
| Manitou Incline | 4.00 mi · 1,929 ft · 170 min · 8,567 ft | 131 bpm · −1.00% | Short, steep exposure; no standalone recovery conclusion |
| Pikes Peak | 14.04 mi · 5,581 ft · 502 min · 14,116 ft | 123 bpm · −1.40% · 20 ppm | Low surrounding HRV context; the retired delta does not prove recovery failure |
| Wheeler Peak | 8.57 mi · 2,996 ft · 307 min · 13,154 ft | 123 bpm · +1.20% · 7.3 ppm | One positive whole-route drift value; not a validated fatigue-reveal signal |
Route, duration, gain, pace, heart rate, exercise load, altitude, environment, metabolic context, symptoms, mechanics, and technical execution.
Sleep, HRV, resting heart rate, stress, soreness, fatigue, symptoms, and time. No single delta certifies adaptation or readiness.
The next relevant effort can support, refine, or contradict an interpretation while remaining observational rather than proof of one mechanism.
The CMS records below preserve individual measurements and historical interpretation. The current one-year audit controls wherever earlier wording conflicts with corrected source columns.
