# Run — 2026-09-02
|
||||||
|
|
||||||
|
**3.01 km in 19:32 — 6'29" pace at 148 bpm. First run after the Aug 29 comeback, morning slot (08:08), no phone, no music. Ran on a tight calf — yesterday's 0-drop shoe experiment put the load on his calves — and it loosened by the 2 km mark. Night-before HRV 145ms (new all-time high) predicted a controlled run, and delivered: mostly aerobic, HR recovery functioning.**

**Splits:** KM 1 — 6'20" · KM 2 — 6'36" · KM 3 — 6'30" · last 0.01 km — 0'06" — remarkably even for a calf-tight run; the loosening showed in km 2–3 holding pace instead of fading.
|
||||||
|
|
||||||
|
**HR zones:** Extreme 0 min · Anaerobic 5 min · Aerobic **10 min** · Fat-burning 2 min · Warm-up <1 min — two-thirds of the run at or below the aerobic ceiling; the 5 anaerobic minutes are the bursts (fastest 5'13"), not the base.

## How it felt

|

|
> "I finally went to bed before midnight for once, but I could not get out of bed at 7 am, I was having dreams until 8 am. Then I got myself together and went for the run. Without music or phone — felt weird. Yesterday I wore my 0-drop shoe, today my calf was sore/short/tight. By the end of the 2 km it was okayish."

||||||
|
**Verdict:** The cleanest data story in the log: bed before midnight → HRV 145ms all-time high → resting HR 48 → the run felt controlled *despite* a tight calf and no pacing feedback. 6'29" at 148 bpm avg is ~6 bpm lower than Aug 15's similar short run at a slower-feeling effort — the recovery was real and the body spent it well. Running without music/phone felt weird, but the numbers say the quiet worked: no feed to chase, HR stayed at 148, splits held even within 16 seconds across all 3 km.
|
||||||
|
|
||||||
|
The calf is the 0-drop signature — switching shoe drop shifts load straight onto the calf/Achilles complex, and yesterday's wear showed up as tightness this morning. It loosened by km 2 and caused no pace fade, so no damage done — but 0-drop deserves the same ramp rule as everything else: don't wear them the day before a run (especially long-run days) until the calves adapt over a few weeks. Note the anti-fade rule survived intact by accident: first km 6'20" was still the fastest (habit), but at 3 km the cost is trivial — this is exactly the kind of run to keep short and boring.
|
||||||
|
|
||||||
|
Watch says 10h recovery — Friday's run is next on the Wed/Fri/Sun clock. Easy week continues.

# Sleep — 2026-09-02

> "I've finally went to bed before midnight for once, but I could not get out of bed at 7 am — I was having dreams until 8 am." First pre-midnight bedtime in a while (23:50), 7h 30min of watch-tracked sleep into a 07:46 rise — the last stretch (7:00–7:46) was dream-soaked REM he didn't want to leave.
|
||||||
|
|
||||||
|
**Interpretation:** The clean-night experiment paid off in the most visible way: **HRV 145ms — above the personal range (74–136ms) and a new all-time high**, beating the previous record of 140ms (Jul 29, light dose). Resting HR 48 is at the very bottom of his range — deep recovery. The bed-before-midnight variable is the standout change from recent nights (Aug 29: 02:14 bedtime → 106ms HRV; tonight: 23:50 → 145ms). Architecture is healthy: deep 31% (2h 21min), REM 12% (53min) back to normal after the sick-week 7%, breathing quality 98. The two flags are cosmetic-to-mild: light sleep 57% (High, ref <55%) and 3 wake-ups — the 7am stirring while dreaming explains at least one of those. The watch's "woke up 3 times" lecture reads scarier than the continuity score (96) suggests; waking out of REM is why 7am felt impossible. Score 85/100, "good."
|
||||||
|
|
||||||
|
**Prediction check vs the morning run:** HRV 145 + resting HR 48 predicted a controlled run — and delivered: 148 avg HR at 6'29" pace with a tight calf, mostly aerobic. See [[Runs/2026-09-02]].
