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 23 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.

7h 30min · 23:50→07:46 · REM: 12% · Deep: 31% · HRV: 145 · Resting HR: 48 · Score: 85/100

First pre-midnight bedtime in a while; couldn't get out of bed at 7am — dreaming until 8am. See Sleep/2026-09-02.

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.
