Heart Rate Features 15
your heart rate data automatically when you begin an
activity. For example, you can broadcast your heart
rate data to an Edge device while cycling, or to a VIRB
action camera during an activity.
NOTE: Broadcasting heart rate data decreases battery
life.
1 From the heart rate widget, hold UP.
2 Select Options > Broadcast During Activity.
3 Begin an activity (Starting an Activity, page3).
The Forerunner device starts broadcasting your
heart rate data in the background.
NOTE: There is no indication that the device
is broadcasting your heart rate data during an
activity.
4 If necessary, pair your Forerunner device with your
Garmin ANT+ compatible device.
NOTE: The pairing instructions differ for each
Garmin compatible device. See your owner’s
manual.
TIP: To stop broadcasting your heart rate data,
stop the activity (Stopping an Activity, page3).
Setting an Abnormal Heart Rate Alert
You can set the device to alert you when your heart
rate exceeds a certain number of beats per minute
(bpm) after a period of inactivity.
1 From the heart rate widget, hold UP.
2 Select Options > Abnormal HR Alert > Status > On.
3 Select Alert Threshold.
4 Select a heart rate threshold value.
Each time you exceed the threshold value, a message
appears and the device vibrates.
Turning Off the Wrist-based Heart Rate Monitor
The default value for the Wrist Heart Rate setting is
Auto. The device automatically uses the wrist-based
heart rate monitor unless you pair an ANT+ heart rate
monitor to the device.
NOTE: Disabling the wrist-based heart rate monitor
also disables the wrist-based pulse oximeter sensor.
1 From the heart rate widget, hold UP.
2 Select Options > Status > Off.
Turning Off Wrist-based Heart Rate While
Swimming
Wrist-based heart rate is turned on by default for swim
activities. The device is also compatible with the HRM-
Tri™ accessory and the HRM-Swim™ accessory. If both
wrist-based heart rate and chest heart rate data are
available, your device uses the chest heart rate data.
1 From the heart rate widget, hold MENU.
NOTE: You may need to add the widget to
your widget loop (Customizing the Widget Loop,
page29).
2 Select Options > While Swimming > Off.
HRM-Swim Accessory
Heart Rate While Swimming
NOTE: If both wrist-based heart rate and chest heart
rate data are available, your device uses the chest
heart rate data.
To view your heart rate data, you can add heart rate
data fields (Customizing the Data Screens, page29).
Heart rate data is not visible while the heart rate
accessory is underwater.The HRM-Tri accessory and
the HRM-Swim accessory record and store your heart
rate data while you are swimming. You must start a
timed activity on your paired Forerunner device to view
your stored heart rate data later. During rest intervals
when you are out of the water, the heart rate accessory
sends your heart rate data to your Forerunner device.
Your Forerunner device 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 device (3 m)
while the data downloads.
TIP: To view your heart rate data while swimming, you
can add heart rate data fields (Customizing the Data
Screens, page29).
Running Dynamics
You can use the pod with your compatible device to
provide real-time feedback about your running form.
The pod has an accelerometer that measures torso
movement in order to calculate six running metrics.
NOTE: The running dynamics features are available on
only some Garmin devices.
Cadence: Cadence is the number of steps per minute.
It displays the total steps (right and left combined).
Vertical oscillation: Vertical oscillation is your bounce
while running. It displays the vertical motion of
your torso, measured in centimeters for each step.
Ground contact time: 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: 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.
Stride length: Stride length is the length of your stride
from one footfall to the next. It is measured in
meters.
Vertical ratio: Vertical ratio is the ratio of vertical
oscillation to stride length. It displays a percentage.
A lower number typically indicates better running
form.
