Wrong pace, wrong distance

I've not had a problem with mine.  I run the same 5k route three times a week and the track and distance has always been correct.  My pace is up and down, but I know that's just me (I have good days and bad days).

i have the same problem. every run I run adds more kilometers than I actually run. I downloaded the running route in GPX format and inserted it into the Locus application. also when I had the missingness corrected in the Strava application, it always shortens it. for example, today they had a trail run with a friend, and the distance and pace didn't suit us. when I corrected the distance via Strava, it already fit almost exactly. I am attaching the link of my run. Garmin shows a distance of 15.4 km and after the repair the distance is 14.32 km. I have a watch 955 solar and software 13.21. connect.garmin.com/.../10025131616 I had this same problem on the 13.15 beta. I reported the problem https://forums.garmin.com/beta-program/forerunner-955-series/public-beta-bug-reports/i/bug-reports---beta-13-15/incorrect-race-distance

I have multi band on

I see that one user is complaining here as well forums.garmin.com/.../wrong-distance-and-pace

Do you have 3D Speed and 3D elevation turned off? I recall seeing somewhere in some post that this may cause issues. one measurements are very close to identical on all platforms and I have not notice any issues in this regard.

I have 3D speed and 3D elevation turned ON. I will turn it off and try to test. thanks for the tip! 

OK will be interesting to see if it changes anything. Good Luck
