Coach's read · whole-athlete
Building under load — CTL 43 (+2.2/wk), TSB -17, recovery 44%. Keep intensity modest today. Your binding limiter is the run: ~0 km/wk (0 runs/wk) against a 25 km short-term target. The bike is ahead of the run — the race is won by closing the run gap, so protect bike fitness but make the run the priority. On the bike, durability is the gap: 1.83 W/kg sustained vs the 2.0 finish-strong target (+0.17).
Deep insights — cross-signals · recovery × load × terrain × weight
🔻What a hard day costs. High-strain days (Whoop ≥14) drop next-day recovery a median -13 pts; easy days (<10) rebound +7 (n=80). Don't stack two hard days — bank an easy day to get the recovery back.
💗Adapting, not overreaching. As fitness built (CTL 30→43), your HRV has dipped under it (27→21 ms). Autonomic system is keeping pace with the load — a healthy build.
🗻Don't panic about EF. Your EF tracks terrain (r=0.63, n=22): flat-ride EF medians 1.08 vs 1.28 on climbs. The recent EF dip is flatter rides, not lost aerobic fitness — judge EF within the same terrain.
⚖️Weight is doing work for you. Down 5.0 kg since spring (92.4→87.3) = +0.10 W/kg toward the 2.0 target at the same power. Of the 0.17 gap, the scale can keep chipping in — keep the trend going.

ACWR 1.38 and HRV 18ms (vs 30d avg 23ms) are moving in the same direction — both signaling accumulated stress. RHR flat at 68bpm week-over-week — stable autonomic baseline. Your data shows a 11-point recovery drop after hard sessions (TSS 100+) vs easy days: 50% vs 62%. Two days post-hard-session, HRV averages 22.0ms vs 24.3ms after easy days — the autonomic suppression is measurable and specific to you.
RECOMMENDATION
Hold intensity today — Z2 only. Your TSB is already negative and two consecutive moderate days is the typical ceiling before HRV dips in your data. Banking Z2 volume here is not a wasted day; it's when aerobic base adaptation happens.

Last night: 8.9h / 90% performance / SWS 2.69h / REM 1.4h. 30-night averages: SWS 2.38h, REM 1.58h, efficiency 94.7%. Last night SWS 2.69h (30d avg 2.38h) / REM 1.4h (30d avg 1.58h) — below personal norms. Expect slight HRV suppression today. 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 16.75 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.
RECOMMENDATION
Sleep architecture is your strongest recovery asset. SWS 2h+ is rare — most trained athletes average 1.0–1.5h. Protect it: consistent wake time ±30 min daily, room 18–20°C, no training within 3h of bed. Current architecture supports continued CTL build.

TRAINING BALANCE — LAST 4 WEEKS
LOAD → NEXT-DAY RECOVERY (60d)
HRV vs CTL FITNESS (60d)
With 230 days to race day, sport balance is Cycling 81% / Running 0% / Swimming 8% — 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 43 requires +0.7 pts/week average to reach 65 by Jan 2027 — achievable at current build rate.
RECOMMENDATION
The single highest-leverage action right now: add 1 easy run/week immediately to stop the economy decay, then scale to 3/week by September. Close the running (+30% gap from target) and swimming (+7% gap from target) volume gap by Oct — not before, or it disrupts the cycling priority block. Swimming: 1 technique session/week now (not fitness — technique). At 70.3 Ironman pace, swim is ~30 min — economy matters far more than fitness here. Cycling: maintain current priority through Aug, then shift to multi-sport balance in the Sept build. Finish-strong target: hold 2.0 W/kg across the 90 km bike. You currently sustain 1.83 W/kg on 30 km+ rides — close the remaining 0.17 W/kg with sustained tempo work.

PERFORMANCE MANAGEMENT — CTL · ATL · TSB (180 DAYS)
CTL rose 37 → 43 in 15 days (+6.3 pts). That's 2.9 pts/week — within the sustainable band of 3–4 pts/week. TSB has averaged -11 over the last 14 days, ranging -45 to +7 — in the recoverable zone. ACWR 1.38 is in the caution zone (>1.2) for 5 days. Not yet dangerous but trending toward overreach territory.
RECOMMENDATION
Hard days in your data drop next-day recovery by 11 points vs easy days (50 vs 62). At TSB -17, one more quality session this week then mandatory de-load — bring ATL below 48 and TSB above −10 before the next block. CTL target: 65–80 by Jan 2027. At current pace (2.9 pts/wk), you hit 65 around Sep 2026. Sustainable path: 3–4 pts/wk gain through Oct, then a 3-week de-load before the build phase begins. Protect easy days — the aerobic base built in Z2 now is what race-pace tolerance is built on.

The run is effectively dormant — 66 days since your last logged run, ~0 km/wk over the last month. This is your race-defining limiter: a 21.1 km leg off the bike is built on weekly run volume, and you're ~25 km/wk short of the Aug Base-1 target of 25. The key insight: your aerobic engine is far ahead of your legs — bike CTL 43 means your cardiovascular system can absorb much more running than 0 km/wk; the limiter is musculoskeletal durability, not fitness. So rebuild frequency FIRST — 3–4 easy Z2 runs/wk (HR <137, ~7:00/km) — before any speed work. Speed isn't the problem: your best pace is 5:06/km against a 4:50/km race T-pace target. Bank easy volume now; sharpen pace in the Build phase.
THIS WEEK
This week: 4 easy runs of 20–40 min at Z2 (~7:00/km, HR <137), with one slightly longer building toward 16 km. No intervals yet — frequency and time-on-feet are the adaptation that protects the legs. Grow weekly volume ≤10%/wk. Add a short bike-to-run brick once you're running 3+×/wk — that's the missing race-specific session.

CYCLING CTL

92% of load
Efficiency Factor (NP/HR) is 1.40 on your last 5 rides vs 1.28 over 8 weeks — the aerobic engine is improving (+9.4%). EF is the truest fitness read here since it needs no FTP. The finish-strong gap is the headline: you sustain 1.83 W/kg on 30 km+ rides against the 2.0 W/kg target — 0.17 to close. Encouragingly, power holds up as rides lengthen, which is exactly the durability race day demands. Distance is largely solved — longest 108 km of the 90 km leg. Pacing is surgy (VI 2.53); on long rides, smoother output will leave more for the run. Cycling-specific fitness (cyc CTL 40) is 92% of total load — the block is cycling-led, as intended.
RECOMMENDATION
Close the 0.17 W/kg gap with structure inside the weekly long ride: 2×15–20 min at ~175 W (2.0 W/kg), progressing to 3×20 min by August — this trains time-at-target, not just distance. Hold the long ride steadier (target VI < 1.15): smoother power is more economical and protects the run. Skip FTP testing this block — EF and sustained long-ride NP/kg are your truer signals.

⚠ Open-water sessions logged: 0 — sighting, wetsuit and mass-start are untrained race variables. CSS shown is a proxy from your best session pace; run a formal test to set it properly.
Swim volume is ~1.2 km/wk (1×/wk). Distance isn't the worry — you've swum 2.5 km in one session vs the 1.9 km race leg. The two real gaps are sharper: (1) CSS is unverified — your best recent pace is ~2:15/100m but you've never run a formal CSS test, so race pacing is guesswork; (2) zero open-water sessions — all pool, so sighting, wetsuit feel and mass-start chaos are completely untrained. Swim gains are frequency-driven, not volume-driven: 3×/wk with technique focus beats one long grind. Your race CSS target of 1:58/100m would put the 1.9 km swim around 37 min.
THIS WEEK
This week: swim 3×. One is a CSS test — warm up, then 400 m time-trial, rest 5 min, 200 m time-trial; CSS pace = 200 ÷ (T400 − T200). One technique/drill session (frequency builds feel for the water). One aerobic 1.5–2 km continuous. And book your first open-water session this month — it's the single biggest unpracticed race variable.

⚠ VO₂max is untested — it's the #1 longevity predictor and your aerobic ceiling. Set it with a field test (Cooper 12-min run or a ramp test). Body-fat 7% world-class rung is a healthy elite floor, not a target to undercut.
Body fat 25% (Withings) vs a 14% race target and the ~7% elite-male floor. Weight is a free W/kg lever: down 5.6 kg since spring has already added +0.11 W/kg at the same power — and every further kg ≈ +0.02 W/kg toward the 2.0 finish-strong target. Protect muscle (61.9 kg) through the cut — protein 1.6–2.0 g/kg/day; dropping weight by losing muscle costs power. Lean, not just light, is the goal.

SpO₂ 92% at 2240 m — normal acclimatized range. Altitude cuts both ways: a natural hypoxic stimulus that lifts your aerobic ceiling, but it also caps overnight SpO₂ and depresses HRV (same reason the HRV targets are altitude-adjusted).
