Chronic Training Load (CTL) Calculator

Calculate your Chronic Training Load (fitness) using an exponential weighted average of daily TSS over 42 days. Track long-term training adaptation

Each component has a specific meaning:

• Exponential weighted average of daily TSS over 42 days — The exponential weighted average of daily tss over 42 days recorded for the scenario being assessed.

Note: Interpret the chronic training load (ctl) result against the thresholds and context described above.

Enter the exponential weighted average of daily TSS over 42 days for the scenario you are assessing. Calculate your Chronic Training Load (fitness) using an exponential weighted average of daily TSS over 42 days. Track long-term training adaptation. Use the chronic training load (ctl) result to inform your calculation.
