Hyrox Race Autopsy — 200,000-Finisher Split & Variance Diagnostic
Powered by the Struggl Hyrox Pace Decay Subsystem and POST /v1/public/autopsy. Benchmarks your 8x1km run splits and 8 functional workout stations against division percentiles and variance gaps (`HYROX_VARIANCE_GAPS_MIN`).
- Compromised Running Decay (`compute_empirical_hyrox_decay_factor`): +17.2% over standalone 5K pace for 17:00 runners, +19.0% for 20:00 runners, +20.5% for 22:30 runners, +22.0% for 25:00 runners, and +24.0% for 35:00 runners.
- 8-Lap Fatigue Multipliers (`LAP_FATIGUE_MULTIPLIERS`): Lap 1 = 0.94x (start adrenaline), Lap 2 = 0.97x, Lap 3 = 1.00x, Lap 4 = 1.01x, Lap 5 = 1.03x (post-Burpee Broad Jump peak slowdown), Lap 6 = 1.02x, Lap 7 = 1.01x, Lap 8 = 1.02x.
- High-Variance Decisive Stations (`HYROX_VARIANCE_GAPS_MIN`): Sled Pull (4.1 min spread between P25 and P75), Burpee Broad Jumps (3.8 min), Wall Balls (3.2 min), Sled Push (2.9 min), Sandbag Lunges (2.8 min).
