Pikes Peak produced the widest separation between performance and recovery in the HikeWorldModel. The effort was the largest in the record: 14.04 miles, 5,581 ft of gain, and 502 minutes at a peak elevation of 14,116 ft. Yet the in-effort engine remained exceptional: Average HR: 123 bpm Maximum HR: 147 bpm HR drift: −1.40% Anaerobic training effect: 0 End ketones: 20 ppm The body completed its longest and highest-gain effort with the lowest average heart rate of the Colorado sequence. Metabolic switching remained near the dataset ceiling, and cardiac economy showed no obvious sign of the recovery strain developing underneath it. The governor told the opposite story. Pikes began with zero REM, suppressed HRV, elevated resting heart rate, and accumulated load from Elbert and Manitou. The first post-hike night brought 552 minutes of sleep, but the long duration reflected recovery demand rather than restoration. HRV remained at 28 ms, resting heart rate rose to 69 bpm, and overnight stress reached 43. Day 2 still did not close the loop. HRV rose only to 30, resting heart rate remained elevated at 64, REM fell to 10 minutes, and overnight stress climbed further to 48. That is the defining Pikes signal: The engine remained capable of ceiling-level performance after recovery capacity had already been exceeded. Unlike Elbert, the acute strain did not resolve within 48 hours. Pikes was tolerated during the hike but not absorbed afterward. This was not a weak performance. It was a strong performance produced by a system that had become unbalanced. Pikes proved that summit success is not the same as recovery readiness.
