Vertical Oscillation and Vertical Ratio Data
The data ranges for vertical oscillation and vertical ratio are slightly different depending on the sensor and
whether it is positioned at the chest (HRM-Pro series, HRM-Run
™
, or HRM-Tri accessories) or at the waist
(Running Dynamics Pod accessory).

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-Pro series accessory.
Accessories with running dynamics have on the front of the module.
• Pair the running dynamics accessory with your watch again, according to the instructions.
• If you are using the 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: Ground contact time and balance appears only while running. It is not calculated while walking.
REMEMBER: Ground contact time balance is not calculated with wrist-based running dynamics.
Chest Heart Rate While Swimming
The 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 (
).
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.
Using an Optional Bike Speed or Cadence Sensor
You can use a compatible bike speed or cadence sensor to send data to your watch.
• Pair the sensor with your watch (
Pairing Your Wireless Sensors, page 61
).
• Set your wheel size (
Wheel Size and Circumference, page 113
).
• Go for a ride (
).
