Wrong pace value on treadmill activity after 8.40 firmware update on Fenix 5x plus

Hi,

After the upgrade of my Fenix 5x plus to 8.40 firmware, my pace, and the distance in consequence, is too way off on a treadmill running. It seems that this upgrade wipe out the calibration that I done before.

It was a 6k running and the watch showed 7.75k (I do not use a foot pod)! Before the upgrade the error in my treadmill runs was in the order of +/-150 m.

Another issue to mention is that the battery has drained 2% (too fast in my opnion) in 45 min of activity (6k treadmill running and strenth workout) without GPS or Music, only sync with the phone and the RD pod.

So I guess the question then would be: Did you do a new calibration, and did it solve the problem?

Yes, I just did and It seems a way better (I did 3x runs of 2k km)

The problem is, if this data was wipe out what else was deleted?

Good point.

It's always worth having a glance at your personal settings like pulse zones, height/weight etc. after updating. I've heard people saying they happens to reset, although I've never experienced it myself.

The only thing I could think of is if the update changed something in the treadmill activity that meant it had a different calibration algorithm and needed to recalculate on fresh data. But in that case it should have said something like ‘please recalculate calibration’ so yeah not good.

There is something very wrong... today I ran again in a treadmill and the pace was too off but near twice as slower than the real pace, not faster like was before. The strange thing is that it seems that it is showing the pace in min/mil but saying that ir min/km. Ex. I ran at ~4:xx min/km and the watch showed 7:xx min/km.

I double checked the configuration, it seems ok.

I know there's a weird thing sometimes with autolap. Is autolap set up for the correct unit

I had a weird bug where for some reason although I work in K it was lap'ing in miles - and it turned out the autolap setting was set for 1.6K (a mile)

Yes, it is set in 1.00 km

Will anybody from Garmin give me an answer?

Best best may be to use the contact us link on the web page to email. I've found them reasonably quick.

As this is a user support forum, sometimes a post gets lost in the mass, so to speak...
