Heart Rate While Swimming

NOTE: Wrist-based heart rate is not available while swimming.

The HRM‍-‍Tri™ accessory and the HRM-Swim™ accessory record and store your heart rate data while swimming. Heart rate data is not visible on compatible Forerunner® devices while the heart rate monitor is underwater.

You must start a timed activity on your paired Forerunner device to view stored heart rate data later. During rest intervals when out of the water, the heart rate monitor 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 monitor must be out of the water, active, and within range of the device (3 m) while data is downloaded. You can review your heart rate data in the device history and on your Garmin Connect™ account.
