Time in Zone Heart Rate Feature

The Time in Zone feature offers the ability to view heart rate zones on a Garmin device or on a chart within Garmin Connect. This feature easily identifies the duration spent in each specified zone during an activity.

To view Time in Zone on a device, review the Training section in the device's owner's manual.  

If a Garmin device does not support the Time in Zone feature, Garmin Connect may still display a Time in Zone chart if the activity includes heart rate or power data. In this case, the data in the chart will be based on the heart rate and power zones in the User Profile settings of Garmin Connect. For more information, see Related Content . 

To view the Time in Zone chart in Garmin Connect open the activity you want to see.

On the web scroll down till you see the Time in Zones tab:

In the Garmin Connect app, open the activity you want to view and tap the icon circled in red in the image below, then scroll down to find the Time in Zones chart:
