Fenix 5X records wrong distance

For about 4 weeks i have a strange problem with my fenix 5x and i cant find it. Sometimes when i record a bike activity the watch doesnt record speed from my speed sensor (i already reconnected the sensor and re-paired it with the watch) and so my recorded distance is completely wrong.

But shouldnt the watch take the distance from gps and not from the speed sensor?

I have shared one of my activities here:
https://connect.garmin.com/modern/activity/3534568264

my girlfriend recorded the same course but got a distance of 76,4 km

Is my speed sensor broken or is there something wrong with the watch?

  • Looks like its dropping out, so your losing both recorded speed and distance. Did you try changing the battery in it?

    Both speed and distance come from the sensor - well at least they do from my Garmin one.
  • Move speed sensor to front hub and replace battery

    I am experiencing similar problem with my Fenix5x , when I connect it to the GPS it goes green and then I press start , it doesn't record the distance at all . It happened to me twice this week and again this morning , The stranger part of it is that when I stop the activity and press save , the saving goes around and around for about one hour and it does not save altogether.

    I tried , when it first occurred, to switch off the device and sync with the wifi with my Garmin Connect ( that is what I use for syncing updates ), it worked once and then it started again giving me the same problem , that is no record of distance and no saving of activity.

    Can someone help me to sort it out ?The activity was running btw.
