# Run — 2026-09-10

**4.05 km in 26:52 — 6'38" pace at 154 bpm. Bonus Thursday: off-plan, 24 h after the week-2 opener, fasted (no breakfast, no caffeine). Both achilles tight-sore for the first few kilometres, a deliberate walk break after 2 km (km 3 = 7'27"), light numbness in both feet over the last 500 m. His own verdict: *"Felt better actually."* The cost of the extra day shows up in HR — 154 bpm at an easy pace, 14 anaerobic minutes — not in a crash: he walked when he needed to, resumed, and ran his second-fastest kilometre straight after the walk.**

## Data

| Metric | Value |
|--------|-------|
| Distance | 4.05 km |
| Duration | 26:52 |
| Avg pace | 6'38" /km |
| Fastest pace | 6'18" /km (km 1) · 4'54" burst (Performance widget) |
| Avg HR | 154 bpm |
| Max HR | 169 bpm |
| Cadence | 162 spm (max 177) |

| Metric | Value |
|--------|-------|
| HR recovery (2min) | 24 bpm (dropped 24, 165→116) |
| VO₂Max | 46 ml/kg/min (maintained, "average") |
| Steps | 4,379 |

**HR zones:** Anaerobic **14 min** · Aerobic 9 min · Fat-burning 2 min · Warm-up <1 min — 14 of 27 minutes above the ~152 aerobic ceiling at a 6'38" average. Splits: 6'18" → 6'29" → **7'27" (the walk)** → 6'20" + 0.05 km (0'18") ≈ 26'52" total. Training load 53 (low), watch says 16 h recovery — down from 21 h after Sunday's long run.

## Sleep — Night before

**8h 26min** · 00:10→08:56 · REM: 9% · Deep: 39% · HRV: **123** · Resting HR: 49 · Score: 91/100

> Score **91 — new best in the log** (beats the 90 of Jul 20), better than 99% of users. Deep 39% (3h15, continuity 95) is the repair-heavy shape; REM 9% is the second night running under 10%, still catching up from the Sep 7 crash night. HRV 123 high-normal — a clean base, just a late (00:10) bedtime. See [[Sleep/2026-09-10]].

## How it felt

> "Both achilles tight-sore for the first few kilometers. After 2 km i walked a bit. No breakfast or caffeine, light numbing around the last 500m. Felt better actually."

*(**Achilles:** bilateral, tight-sore, first few km — **third consecutive run** with achilles-adjacent tightness and the first bilateral report (Sep 6 left achilles, Sep 9 calf-achilles, Sep 10 both). It loosened enough to run km 4 at 6'20", so it's still the warm-up pattern — not point-pain. **Feet:** light numbness over the final 500 m = the logged pattern (3–4 km trigger, sole/transverse-arch, resolves on stopping), and 4.05 km is the Jogflow 190.1's stated ceiling. **Fasted:** no caffeine means 154 bpm isn't a stimulant artefact; at 4 km the fuel question is minor — it reads as back-to-back legs, not an empty tank.)*

## Comparison

| Metric | Sep 2 (controlled) | Sep 4 (hot overshoot) | Sep 6 (long, taxed) | Sep 9 (ego leak) | **Sep 10 (today)** |
|--------|--------------------|-----------------------|---------------------|------------------|--------------------|
| Distance | 3.01 km | 5.04 km | 6.07 km | 3.24 km | **4.05 km** |
| Duration | 19:32 | 36:31 | 41:59 | 19:21 | **26:52** |
| Avg pace | 6'29" | 7'15" | 6'55" | 5'58" | **6'38"** |
| Avg HR | 148 bpm | 159 bpm | 157 bpm | 157 bpm | **154 bpm** |
| Max HR | 163 bpm | 176 bpm | 179 bpm | 180 bpm | **169 bpm** |
| Cadence | 166 spm | 156 spm | 161 spm | 168 spm | **162 spm** |
| VO₂Max | 46 | 46 | 46 | 46 | **46** |
| Sleep HRV | 145ms | 111ms | 74ms | 127ms | **123ms** |

At the same effort band (154–157 bpm) today ran **40 s/km slower than yesterday** and **9 s/km slower than the rested Sep 2 benchmark** — the price of a second consecutive day, which is the first back-to-back pair in the log (Sep 2, 4, 6, 9, 10 — always ≥48 h apart until now).

## Physical notes

- **Achilles — watch item, escalating.** Third run in a row with tightness in the calf/achilles complex, and the first time it's both sides. Consistent pattern: sore for the first 2–3 km, then it goes quiet (km 4 was 6'20", fastest km of the run after the walk). That's the warm-up signature — manageable, not alarming. The escalation trigger is what it's stacking on: Sunday's 6.07 km load + Wednesday's surge + today's bonus day, with the 7 km long run arriving in 72 h. Mobility floor tonight and tomorrow: ankle circles, gentle calf work, and if it's sore at tomorrow's warm-up, the run goes to a walk.
- **Foot numbness → the shoe task.** 4.05 km is exactly where the Jogflow 190.1 runs out, and the numbness arrived in the last 500 m. The skill's standing hypothesis is lace compression over the midfoot; before spending on the stability pair, **relace for Sunday** — skip the midfoot eyelet (wide-lace over the transverse arch) or loosen that crossing one notch. If the 7 km is numbness-free, the compression cause is confirmed and the current shoe bought a reprieve (Jogflow still can't carry 8 km+ from Sep 14). If it still goes numb, the shoe purchase moves up the list.

## Verdict

**The run nobody required, done the way the plan asks.** This was a bonus day — week 2's floor is Wed / Fri / Sun, and two of those are already banked (Sep 9 + this + Sunday's long run = 3) — so the only thing today had to prove was that the middle path exists. It does: he walked at 2 km instead of pushing through, and instead of the walk ending the run it reset it (6'20" was the second-fastest km of the day). Three runs ago (Sep 9) the same instinct produced a 400 m ego surge; today the same instinct produced a walk break and a resume. That is the exact behaviour the plan pays for — *walking is allowed, time on feet beats pace* — used as a tool instead of treated as failure.

The numbers say what it cost, honestly, without it being a problem: **24 h legs + fasted = +9 s/km at +6 bpm versus the rested benchmark**, 14 anaerobic minutes at an easy pace, VO₂Max flat at 46 and HR recovery at 24 bpm (his usual 18–24 band, so the recovery engine is untouched). And the sleep behind it was the **best-scoring night in the log (91)** — the base was not the constraint today, the schedule was. *"Felt better actually"* is the sentence worth keeping: after weeks of runs that felt worse than they looked, this one felt better than it looked.

**Two context notes.** (1) Still inside the quit-craving window (Sep 9–13) and he ran through it again — the tool keeps getting used. (2) The one thing genuinely worth deciding is Friday: the floor is already met, Sunday is 7 km, and the achilles is the first thing in this log that is trending the wrong way. A skipped or 2–3 km shuffle on Friday costs nothing; a fourth consecutive run costs the long run, which is the actual goal.
