Fenix 5X incomplete track record

Hello,

Today I ran a round-trip route with my Fenix 5X.  I started and stopped at the same place, which is marked by the 'play' button at the top of the map.  However, the route record stoped at around 2/3 of the activity, as indicated by the 'stop' sign at the bottom of the map.  Strange enough, the total time, distance, and HR records I believe should be somehow correct.  It seems only the lat/lon and other related records are incomplete.

Actually this is not the single case, I have another round-trip run previously and the same thing happened.  The track record on the map showed I stopped in the middle of the path but actually I ran back to where I start.

Do you have a hints on this issue?  Any help is appreciated and thanks very much!

  • When it loses satellite signal then the distance is incremented by the accelerometer, the same sensor as used for treadmill workouts. That explains why the distance/time/HR are still recorded. But why you lost GPS signal I don't know, at the very least I thought it would catch it again when you came out of the trees near the finish. You can show a data field for GPS signal strength, it's in Other Fields > GPS to monitor the GPS connection during a run.

  • Hi Carleson, thanks very much for the explanation. Since Both of the activities are round-trip routes in open area without dense tree coverage and buildings around, it seems that the watch just lost signal during the return trip is quite an unacceptable behaviour.  Imagine for a 100k/mile running record and the watch just cannot record where you are for half of the track, or lose signal during your run.  It seems that there is not much we can do about it, though.

  • I've had it on occasion on an out and back where I paused the watch on  the turnaround and then on the way back it was north facing and I was moving and it never got signal back, but that's like once in 15 years. If environment can't be blamed or you didn't have something covering it like a shirt or jacket sleeve then I'd suggest there is something wrong with the watch. To help monitor this, I suggest installing this CIQ field and it will write the GPS quality into the watch data and is then viewable on Garmin Connect as a graph of your activity data: https://apps.garmin.com/en-US/apps/e3f85a7a-7241-4fd1-b6b3-39eddf26ed43

  • Thanks for the CIQ link. I'll install the app and have a check on the record if the track is off/disappeared again.  At the moment I think what I can do is just going out for a run.
