Garmin Fenix 5 Plus: ‘Auto Pause’ Messed Up My GPS + Glonass Distance By About 0.25 Mile!

Compare with map below. Same route.



Today for the first time I had ‘Auto Pause’ enabled on my Garmin Fenix 5 Plus. I went for one of my usual runs — with my two dogs (Golden & Harrier) who do like to stop OFTEN. So, yes, auto pause was kicking in and off — quite often.

This is a run I do, on average twice a week, and have done so for nearly a year. I have run it while wearing: Garmin Vivoactive 3, Fitbit Ionic, Garmin Fenix 5, Garmin Fenix 5 Plus & Polar Vantage V. So, I know what the distances are and do so across multiple watches. I also do this run most of the times with the dogs.

Thus, the only change today was ‘auto pause’. I get to the driveway of my friends’ — and you can see the little squille (top right) when I detoured to see them on a prior run. The GPS reading should have been around 1.6 miles. Today, it was not. Close to 1.5. That was wrong. I ran to my usual 1.75 point. It read 1.6! I ran further. This was further than I have ever run on this route before. I got to 1.65 miles. I gave up. Turned around. I knew I had done 1.75+ miles.

Came home. Didn’t make any detours. Straight back and you can see that. When I got home it read 3.53 miles!

Ah!

I had turned around 1.65 miles. 1.65 x 2 is 3.3 NOT 3.53.

So, obviously GPS was catching up on the way back.

NOT AMUSED. Turned auto pause off. Screw that for a game of checkers.
