Problem calibrating treadmill

From the manual:

  1. Start a treadmill activity (Starting an Activity).
  2. Run on the treadmill until your Instinct® device records at least 1.5 km (1 mi.).
  3. After you complete your run, press GPS.
  4. Select an option:
    • To calibrate the treadmill distance the first time, select Save.

      The device prompts you to complete the treadmill calibration.

    • To manually calibrate the treadmill distance after the first-time calibration, select Calibrate & Save > Yes.

  5. Check the treadmill display for the distance traveled, and enter the distance on your device.

For a first time calibration:

Following a session I got as far as 3.1 ie select Save and I was expecting some prompts but...

... the activity was saved and there were no prompts!

Can anyone shed some light on this please?

    If you don't get an opportunity to Calibrate&Save at the end of an activity on the Instinct you can still adjust the total distance in the Connect app or web page.

    I've never been able to get Calibrate&Save to actually calibrate the treadmill activity. Yes, it allows me to set the correct distance from the treadmill display. But successive Treadmill activities show random distances that never converge on what the treadmill actually displays (and that I know to be accurate.) So I have no idea what I'm "calibrating" using the C&S procedure.

    For a standard 5km treadmill distance my Instinct will show random values ranging from less than 1km to over 7km no matter how often I do a C&S. I've reached out to Garmin support a few times but they were of no help in resolving this.

    So now I just do a manual C&S every time.

  • Followup: I just did ~66 minutes on a treadmill at a constant 6.2km/hr. That should be 66/60*6.2=6.82. The treadmill showed 6.80.

    The Instinct shows:

    1km: 43:58 min

    2km: +12:43 min

    3km: +6:49 min 

    3.35km: +2.54 min

    So despite daily "calibration" for several months today it says it took ~44 min to do the first km, then ~13 min to do the second km, then ~7 min to do the third km. This even though the treadmill was set to 6.2km/hr for the duration of the session.

    As you can see this makes absolutely no sense.

  • Thank you for your reply.

    Tried again this morning and the same result.

    I'll just edit the distance post activity - no big hardship.
