## Sleep — Night before
|
||
|
||
**5h 52min** (watch) + **~50min post-wake nap** → ~6h 42min total · 01:36→07:50 · REM: 19% · Deep: 23% · HRV: **93ms** · Resting HR: 54 · Score: 72/100
|
||
|
||
> Short night — only 5h 52min, below the 6-10h reference range. Light sleep dominated at 58% (above the 55% reference — sign of restless/compensatory light sleep). Woke 2 times. HRV at 93ms is within range (78-132) but well below your sober baseline (110-135ms) — comparable to your ~2-drink nights. Deep sleep 23% is technically normal but that's only 1h 21min of actual deep sleep on such a short night. You napped ~50min after waking, bringing total sleep to ~6h 42min — still below your ideal. Breathing quality held at 98, SpO₂ 98%.

## How it felt
|
||
|
||
> Really wasn't feeling it today. Hard day mentally — lot of clutter in my head. At the end of the workday I decided to just go for a run, see if it would clear things out. Ate 2 muesli bars beforehand and made my sports drink (30g sugar + pinch of salt in water).
|
||
>
|
||
> The heat was killing me though. Afternoon sun + summer temps made it a slog. Combined with the short sleep and mental fatigue, this was pure grind — not a fun run by any stretch. But I finished it.

**Verdict:** Second 5K in the books — and you finished it. But the numbers tell a clear story: **same average heart rate (155 bpm) as Jul 5 but 39 seconds slower per km**. That's a significant efficiency drop driven almost entirely by sleep. You ran Jul 5 on 8+ hours of sleep with HRV at 135ms (top of range); today you ran on 5h 52min with HRV at 93ms. The cadence drop (156 vs your usual 165-172) and higher max HR (178, matching your all-time peak) suggest your body was working much harder to produce less output — classic under-recovered physiology. HR recovery was also weaker: 21 bpm vs 25 bpm on Jul 5.
|
||
|
||
The bright side: **VO₂Max held at 41**, you finished the full 5K without stopping, and you kept perfect 50/50 balance. The afternoon timing (17:52) + summer heat + mental fatigue were a triple headwind — your body is used to morning runs in cooler conditions. This was a grit-finish, not a performance run — and sometimes that's the kind you need. 🏃
