Why is only the last segment of run visible on map?

On the Gamin Connect map I can only see the last segment of various runs. GPS signal was present since start.

I have automated Stop/Start when no position changes are detected for a while (f.e. waiting in front of traffic lights)

My guess is it is only showing from last automated start (after automated stop) until the final stop.

I have this on various runs, while f.e. the whole data for a 7km run (heart rate, distance etc.) is visible, only the very last few hundred meters of the track show up un the map. This fails on the Web and also when later viewed on the iPhone. I am syncing via Windows with a Cable.

Any ideas or am I missing just a checkbox or something?

  • Open an activity's file in some other editor/viewer to be sure what part of a run it contains, you can try different formats.

    On some watches there is no status for GPS during activity, it shows only at start as a pop-up and disappears fast after lock, it's needed to get DataField from the store to see it normally. So make sure you have signal all the time during activity.

  • Pretty sure this is NOT a GPS problem, that is why I initially wrote this. I was already running for 6km outside and checked my location on the map multiple times. I will try to have a look at the file somehow, but please assume this is NOT a GPS problem. My guess is, it looks for a Start-Position and a Stop-Position and if multiple Starts and Stops are found, the last in List is taken. And the automated Start/Stop while no position change is detected creates many Starts and Stops.

    Also the Activity contains the whole run, all other data is present. When I press the Play-Button a cursor runs through the data but shows up in the partial track only in the last 10%

  • Yes, so as first I suggested to check a file. It's possible that it's rendered wrongly and other viewer may show more, or even you can open raw data to check it manually what positions are saved.

  • Thank you. How can I access the file and what alternative viewer do you suggest? My guess indeed is a rendering error with Garmin Connect.

  • You can export different formats FIT, GPX etc. using the gear icon on full activity's page. To be sure that converted formats by the website are correct, you can convert on your own original FIT file, for example by GPSBabel.

    Then open is some editor/viewer.

    There is a lot of them, some are standalone, others online. I usually use JOSM editor, which can be also used to edit OpenStreetMap, but it's simple for GPX, basically just showing a path, for sure there are others more advanced which show more data for sports.

  • Will use Visual Studio Code if it's just Json data Wink

    PS: Oh wait, Josm... hope it is only a scheme for Json data...
