80/20 Zone Calculator
If you have one of our 80/20 Endurance training plans, your custom training zones are auto-calculated directly within each workout. Otherwise, use this calculator to find your individual intensity zones. For details on determining LTHR, TP, CV and FTP, and for the definition of each zone, see the intensity guidelines. You don’t need an 80/20 training plan or a TrainingPeaks account to use the calculator. Consider using the 80/20 Zones Garmin app to increase your workout efficiency.
Running and cycling
Test and calculate your bike and run zones separately — they are not the same.
Enter your test result above and your zones appear here.
