The split signal here is meaningful: ACWR is 1.24 (technically overreach territory) but HRV is 26ms — +5ms above your 30-day norm. This divergence means your cardiovascular system is handling the load, but the cumulative fatigue debt (2 days above 1.2) will show up in HRV suppression within 3–5 days if load isn't managed. RHR dropped 2bpm week-over-week to 65bpm. Falling RHR alongside stable/rising HRV is the adaptation signature — aerobic efficiency is improving. Recovery response to load is consistent across session types in your data.

Last night: 6.2h / 74% performance / SWS 2.27h / REM 1.84h. 30-night averages: SWS 2.37h, REM 1.51h, efficiency 94.3%. SWS 2.27h and REM 1.84h last night are both at or above your 30-day avg (SWS 2.37h, REM 1.51h) — architecture is solid. Sleep performance and next-day HRV show weak correlation in your data — your HRV response is more load-driven than sleep-driven currently. Resp rate 16.86 brpm is elevated — sustained >16 brpm is an early overreach or illness signal. Watch for convergence with rising RHR and falling HRV over the next 72h.

With 260 days to race day, sport balance is Cycling 80% / Running 0% / Swimming 5% — target is 55/30/15 for a 70.3. Running exposure last 4 weeks: 0 sessions — running economy risk is CRITICAL. Running fitness decays at ~1%/week without stimulus. Zero sessions in 4 weeks means 4–6%+ economy loss — a direct hit to race-day run split. This is the highest-priority gap to close, not cycling. CTL 37 requires +0.8 pts/week average to reach 65 by Jan 2027 — achievable at current build rate.

CTL rose 36 → 37 in 15 days (+0.5 pts). That's 0.2 pts/week — within the sustainable band of 3–4 pts/week. TSB has averaged -16 over the last 14 days, ranging -33 to +1 — in the recoverable zone. ACWR 1.24 is in the caution zone (>1.2) for 2 days. Not yet dangerous but trending toward overreach territory.
