Training Analysis & Recommendations
Based on your last 90 days · Updated Apr 21, 2026
Where you are right now

Your CTL of 42 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 26 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 +14 means you are recovered and fresh — a good time for quality work. Your ACWR of 0.86 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 85 remains the long-term target.

What to do this week

With TSB at +14, you are ready to push. Do 2 quality sessions this week, each targeting TRIMP 130–160, with easy days between. This is your window to make real fitness gains.

The path to CTL 72

You are 30 CTL points away from a target of 72. At a realistic build rate of 3–5 points per month — requiring consistent weekly TRIMP of 550–650 — you could reach CTL 72 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.
