**The brain was checked out.** Light sleep at 68% (vs <55% ref), REM at 11% (only 1 hour), no dreams. Your CNS is still processing the festival's sensory overload + chemical assault + 150K steps. The "reflex" quality of this run — not wanting to go, no motivation, just muscle memory taking over — is telling. Sometimes the body performs best when the mind isn't overthinking. **The brain was checked out.** Light sleep at 68% (vs <55% ref), REM at 11% (only 1 hour), no dreams.

**The max HR of 180 bpm is a new all-time high** (previous: 178 on Jul 13 and Jul 15). But context matters: this isn't distress — it's the heart responding to a genuine effort at high pace. You touched 4'04\" instantaneous and averaged 5'40\" for 3K. That's genuinely fast. **The max HR of 180 bpm is a new all-time high** (previous: 178 on Jul 13 and Jul 15). The context: you held ~4'00"/km for about 2 minutes during an intense music section — a genuine surge, not distress. The 27-28°C heat adds ~5-8 bpm of cardiovascular drift on top of that, so in cooler conditions the same effort might've peaked around 172-175.
**Cadence at 164 is the lowest in recent runs** (usual: 170-172). Combined with the fast pace, this means your stride length was significantly longer than usual. Speed = cadence × stride length, so at 10.60 km/h with 164 spm, your stride was roughly 108 cm — up from your typical 95-98 cm. This might be a form adaptation from all the walking at the festival (35K-step days build different motor patterns) or it could simply be that you were pushing hard and lengthening your stride to hit the pace instead of spinning faster. **Cadence at 164 is the lowest in recent runs** (usual: 170-172).
