Treadmill Calibration not working after 22.35

I have never had issues with Treadmill calibration since I have the watch for over a year.

After updating to 22.35 calibration is going nuts!. Even if I calibrate, the following run it is totally off, even after resetting treadmill settings.

Interesting the same issue on my Vivoactive 6 after to latest software 17.33.

Am I the only one?

  • My treadmill activity also disappeared from my quick list and now it doesn't record distance or pace at all, when before the update, it was working just fine and about 95% accurate to what my treadmill was reading. I haven't been able to fix it, it won't allow me to calibrate, and I don't know what else to do. 

  • I am facing the same issue. It seems that calibration algorithm went upside down. 

    I had a session e.g. 7km and watch showed 7.2km, so I calibrate&save the real distance of 7km. Next session instead of 7.2 it was 7.5, next one 8km and so on. Like calibration was asjusting in the wrong direction.

  • Same thing happens with me. When I calibrate it after my run the only thing that is updated is the total mileage/distance. but  even that data in the "Stats" and "Laps" and "Charts" sections are still off. 

  • Same problem here. I never had any issues with calibration before — the recorded distance was always displayed almost accurately. Nothing has changed except for the update (no handlebars, no different arm swing, etc.).

    Now, almost double the distance is being measured and displayed, and my pace is practically cut in half. I noticed that the cadence is still correct, but the stride length has doubled.

    When can we expect a fix for this bug?

  • Honestly, this is an insulting response. I have been using a Forerunner for over a decade. I know that something is wrong after the update. None of my Forerunners have ever been great on the treadmill but the 970 was working well enough when I got it. It was immediately after the last update that everything went bad when dealing with the treadmill. I ran outside last week and it was fine but the treadmill issue is getting worse!

  • In my case, I have recalibrated it after every single run and for the past few weeks, it does not respond at all. The next run (usually same day, same treadmill, minutes later) is just as inaccurate--showing a pace that is almost twice as fast as the actual pace and nearly double the distance of the actual run.

    This is a new problem that started earlier this month (June 6th or so). Prior to that (as in the entire time I have owned this watch) this has never happened. Calibration had always resulted in fairly accurate results (usually off by less than a quarter of a mile) for each treadmill run. 

  • Thank you for posting your concern with the treadmill calibration on the Fenix 8. We are investigating this. I have added those of you here to this ticket. Once there are any other updates or solutions, we will post here again.

  • Hello, i have the same problem after 22.35 sw update. I have over 10 treadmills runs and calibration, also outdoor runs with correct distance. After updating to 22.38 problem is still there. I’m usually running at pace 6. Now my watch is showing pace 3

    Thank you for your reply. I have reported your concern as well.

  • I am also having this problem with my Fenix 8. Very annoying and hope there's a quick fix
