Training load and CTL scenario
Duration and relative intensity can estimate training load, while a rolling model shows how repeated daily load changes a CTL scenario. Enter your values to see the arithmetic and its assumptions. Training load is one signal among many. It does not diagnose fatigue, predict injury or establish a safe weekly increase for every athlete.
Your result, in detail.
Review the assumptions before turning a calculation into a target.
| Measure | Value |
|---|---|
| Day 7 | 41.6 |
| Day 14 | 42.9 |
| Day 21 | 44.0 |
| Day 28 | 44.9 |
Why this number?
Load = hours × intensity factor² × 100. CTL next = CTL + (daily load − CTL)/42. TSS®/IF® are TrainingPeaks/Peaksware references.

Questions, answered.
What does this training load imply?
Duration and relative intensity can estimate training load, while a rolling model shows how repeated daily load changes a CTL scenario. Enter your values to see the arithmetic and its assumptions. Training load is one signal among many. It does not diagnose fatigue, predict injury or establish a safe weekly increase for every athlete.
Does CTL diagnose fatigue?
No. This is a rolling load model. Sleep, symptoms and recovery are not inferred from the load score.
Is the ramp a safe-training limit?
No. An arithmetic scenario does not establish a universal safe weekly increase or predict injury.
What does the result assume?
Load = hours × intensity factor² × 100. CTL next = CTL + (daily load − CTL)/42. TSS®/IF® are TrainingPeaks/Peaksware references.
Is this an exact prediction?
Arithmetic conversions are exact within input precision. Physiology models and planning scenarios are estimates; use the assumptions and your training response.
Can I change units or share this result?
Yes. Unit preference is remembered on this device. The share link includes calculator inputs; review them before sharing.
