I have a Forerunner 45S and I have problems with the Heart Rate Zones (HRZs). I've managed to identify that the HRZs in the Android (and Web) Garmin Connect do not allow me to add/amend max HRZs for any other activities. So the default max HR (and zone) only applies to walking! Is there a way of adding an activity to the 45S or through Connect and associating a HRZs to them?
