Training Analysis & Recommendations
Based on your last 90 days · Updated Apr 27, 2026
Where you are right now

Your CTL of 41 puts you in solid amateur training territory, but there is a clear downward drift. Since your Oct 2025 peak of CTL 68, you have lost 27 points of fitness. You are training 20 of the last 30 days (4.7 sessions/week) with an average TRIMP of 65 per session.

Your TSB of -1 is mildly negative — light fatigue, manageable. You can train hard without needing a recovery day first. Your ACWR of 0.81 is comfortably in the safe zone, so injury risk is low.

The recent trend

The monthly CTL averages: Oct 62 → Nov 58 → Dec 54 → Jan 49 → Feb 45 → Mar 44 → Apr 43. This represents a gradual decline. You never dropped below CTL 37 this year — your base has held. Your all-time high of 84 remains the long-term target.

What to do this week

With TSB at -1, start with 1–2 easy days, then do one quality session targeting TRIMP 112–142 (roughly 60–90 min at moderate-hard effort). This will nudge ATL up without spiking ACWR above 1.3. Repeat the quality session on the weekend — that pattern should bring CTL to around 43–44.

The path to CTL 71

You are 30 CTL points away from a target of 71. At a realistic build rate of 3–5 points per month — requiring consistent weekly TRIMP of 550–650 — you could reach CTL 71 by October 2026–February 2027.

The key lever is not training more days — you are already at 5 sessions per week. It is making 2 of those days genuinely hard, targeting TRIMP 125+ each, while keeping the others truly easy. That polarised approach is what drives CTL growth.
