Time spent in the various heart rate zones is being displayed after a swimming session but not after a run. Is it possible to set the App to do both?
The Heart Rate Zones information is available for all types of activities, runs including. It is on the last screen - tap the icon of the graph, and scroll to the very bottom of the screen. Alternatively, you can also view it on the tab Time in Zones of the activity screen in Garmin Connect Web.
