You can calculate your Training Zones based on your Max. Heart Rate, or the heart rate at the Aerobic/Anaerobic Threshold (AT). A quite reliable but easy way to determine your threshold is to perform a short time trial of at least 20 to max. 30 minutes (after a thorough warmup). Your average heart rate over the net TT time is a good indication of your heart rate at threshold. Alternatively you can enter them manually at the bottom of this page, for example when you have established them in a lab test.
2PEAK will use the Zones you saved to analyze the training data you upload.
This are the zones that are currently saved for you:
