Heart Rate Accessory Running Pace and Distance

The HRM 600, HRM-Fit, and HRM-Pro series accessories calculate your running pace and distance based on your user profile and the motion measured by the sensor on every stride. The heart rate monitor provides running pace and distance when GPS is not available, such as during treadmill running. You can view your running pace and distance on your compatible fēnix watch when connected using ANT+ technology or secure Bluetooth technology. You can also view it on compatible third-party training apps.

The pace and distance accuracy improves with calibration.

Automatic calibration: The default setting for your watch is Auto Calibrate. The heart rate accessory calibrates each time you run outside with it connected to your compatible fēnix watch.

NOTE: Automatic calibration does not work for indoor, trail, or ultra run activity profiles (Tips for Recording Running Pace and Distance).

Manual calibration: You can select Calibrate & Save after a treadmill run with your connected heart rate accessory (Calibrating the Treadmill Distance).

Tips for Recording Running Pace and Distance

  • Update your fēnix watch software (Product Updates).
  • Complete several outdoor runs with GPS and your connected HRM-Fit or HRM-Pro series accessory. It’s important that your outdoor range of paces matches your range of paces on the treadmill.
  • If your run includes sand or deep snow, go to the sensor settings, and turn off Auto Calibrate.
  • If you previously connected a compatible foot pod using ANT+ technology, set the foot pod status to Off, or remove it from the list of connected sensors.
  • Complete a treadmill run with manual calibration (Calibrating the Treadmill Distance).
  • If automatic and manual calibrations don’t seem accurate, go to the sensor settings, and select HRM Pace & Distance > Reset Calibration Data.

NOTE: You can try turning off Auto Calibrate, and then manually calibrate again (Calibrating the Treadmill Distance).

Running Dynamics

Running dynamics is real-time feedback about your running form. Your fēnix watch has an accelerometer to calculate five running form metrics. To view all of the running form metrics, you must pair your fēnix watch with the HRM 600, HRM-Fit, HRM-Pro series accessory, or other running dynamics accessory that measures torso movement. For more information, go to Garmin.com/performance-data/running.

Metric

Sensor Type

Description

Cadence

Watch or compatible accessory

Cadence is the number of steps per minute. It displays the total steps (right and left combined).

Stride length

Watch or compatible accessory

Stride length is the length of your stride from one footfall to the next. It is measured in meters.

Vertical oscillation

Watch or compatible accessory

Vertical oscillation is your bounce while running. It displays the vertical motion of your torso, measured in centimeters.

Vertical ratio

Watch or compatible accessory

Vertical ratio is the ratio of vertical oscillation to stride length. It displays a percentage. A lower number typically indicates better running form.

Ground contact time

Watch or compatible accessory

Ground contact time is the amount of time in each step that you spend on the ground while running. It is measured in milliseconds.
NOTE: Ground contact time and balance are not available while walking.

Ground contact time balance

Compatible accessory only

Ground contact time balance displays the left/right balance of your ground contact time while running. It displays a percentage. For example, 53.2 with an arrow pointing left or right.

Step speed loss

HRM 600 only

Step speed loss is how much you slow down when your foot hits the ground while running. It is measured in centimeters per second. A lower number is typically better, as it indicates you have to do less propulsive work to speed back up.
NOTE: Step speed loss metrics are not available while walking.

Step speed loss percentage

HRM 600 only

Step speed loss percent is how much you slow down when your foot hits the ground as a percentage of your running speed. This accounts for step speed loss typically increasing with faster running speed.

Tips for Missing Running Dynamics Data

This topic provides tips for using a compatible running dynamics accessory. If the accessory is not connected to your watch, the watch automatically switches to wrist-based running dynamics.

  • Make sure you have a running dynamics accessory, such as the HRM 600, HRM-Fit, or HRM-Pro series accessory.
  • Pair the running dynamics accessory with your watch again, according to the instructions.
  • If you are using an HRM 600 accessory, pair it with your watch using the secure Bluetooth connection, rather than the open connection.

For more information about connection types, go to Garmin.com/hrm_connection_types.

  • If you are using an HRM-Fit or HRM-Pro series accessory, pair it with your watch using ANT+ technology, rather than Bluetooth technology.
  • If the running dynamics data display shows only zeros, make sure the accessory is worn right-side up.

NOTE: Some metrics do not appear while walking (Running Dynamics).

Running Power

Garmin running power is calculated using measured running dynamics information, user mass, environmental data, and other sensor data. The power measurement estimates the amount of power a runner applies to the road surface, and it is displayed in watts. Using running power as a gauge of effort may suit some runners better than using either pace or heart rate. Running power can be more responsive than heart rate for indicating the level of effort, and it can account for the uphills, downhills, and wind, which a pace measurement does not do. For more information, go to Garmin.com.sg/minisite/runningscience.

Running power can be measured using a compatible running dynamics accessory or the watch sensors. You can customize the running power data fields to view your power output and make adjustments to your training (Data Fields). You can set up power alerts to be notified when you reach a specified power zone (Activity Alerts).

Running power zones are similar to cycling power zones. The values for the zones are default values based on gender, weight, and average ability, and may not match your personal abilities. You can manually adjust your zones on the watch or using your Garmin Connect account (Setting Your Power Zones).

Running Power Settings

From the watch face, press , select Activities, select a running activity, press , select the activity settings, and select Running Power.

Status: Enables or disables recording Garmin running power data. You can use this setting if you prefer to use third-party running power data.

Source: Allows you to select which device to use to record running power data. The Smart Mode option automatically detects and uses the running dynamics accessory, when available. The watch uses wrist-based running power data when an accessory is not connected.

Account for Wind: Enables or disables using wind data when calculating your running power. Wind data is a combination of the speed, heading, and barometer data from your watch and the available wind data from your phone.

Chest Heart Rate While Swimming

The HRM 600, HRM-Pro series, HRM-Swim, and HRM-Tri heart rate accessories record and store your heart rate data while you are swimming. To view your heart rate data, you can add heart rate data fields (Customizing the Data Screens).

NOTE: Chest heart rate data is not visible on compatible watches while the heart rate monitor is underwater.

You must start a timed activity on your paired watch to view stored heart rate data later. During rest intervals when out of the water, the heart rate accessory sends your heart rate data to your watch. Your watch automatically downloads stored heart rate data when you save your timed swim activity. Your heart rate accessory must be out of the water, active, and within range of the watch (3 m) while data downloads. Your heart rate data can be reviewed in the watch history and on your Garmin Connect account.

If both wrist-based heart rate and chest heart rate data are available, your watch uses the chest heart rate data.
