Training Analysis & Recommendations
Based on your last 90 days · Updated May 02, 2026
Where you are right now

Your CTL of 47 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 21 points of fitness. You are training 22 of the last 30 days (5.1 sessions/week) with an average TRIMP of 71 per session.

Your TSB of -25 signals significant fatigue. Prioritise 2–3 recovery days before any quality work. Your ACWR of 1.18 is comfortably in the safe zone, so injury risk is low.

The recent trend

The monthly CTL averages: Nov 58 → Dec 54 → Jan 49 → Feb 45 → Mar 44 → Apr 43 → May 48. 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 -25, take 2–3 proper rest days first — light movement only. Once TSB climbs back above −10, add one quality session targeting TRIMP 100–130.

The path to CTL 71

You are 24 CTL points away from a target of 71. At a realistic build rate of 3–5 points per month — requiring consistent weekly TRIMP of 500–600 — you could reach CTL 71 by October 2026–January 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 131+ each, while keeping the others truly easy. That polarised approach is what drives CTL growth.
