Lactate test HRM RUN2 + FENIX 5

Hello guys,
I was trying to do the Lactate test within running activity, yet I am unable to start the test. It says I have to connect the HRM sensor. Actually I do have it connected, 'cos I use external Garmin HRM RUN 2 sensor every-time I do running activity.

Do not you know where the problem could be?

Thank you,
tampiss
  • Is it paired? And are you waiting for the HRM to connect before selecting the LTHR test? There should be a message "Ext. HR Connected"

    One way to check for certain is to select the Run app, then physically remove the watch from your wrist. If it is displaying an HR, you know it must be coming from the HRM.

    Actually yes it is paired. I have also tested if the HR is coming from the HRM or watch and it comes from HRM fine. Unfortunately, the test always says the same.
