Fenix 5X Speed Spike on Garmin Connect

hi,

I went for a bike ride yesterday using the bike profile with Garmin HR chest strap ( 1sec GPS recording and watch attached to the bike handle bar). Whilst the GPS map seems OK on Garmin Connect, i could see a max speed of 58mph which is incorrect and the graph shows a spike.

This is disappointing and I would like to know if there is anything i can do to prevent this from happening again? Never had this problem with Fenix 3

Thanks
  • This happens with my Fenix 5X too. I had Fenix 3 and the same happened only one time. However, this is my third Fenix 5X and it happens again. I tried to contact Garmin, sent some Fit files etc. it happens rarely now but in the end it sometimes happens.
    You pause an activity, and when you resume the first second is recorded with a spike. Strava filters these, but neither the watch nor the Connect website doesn't filter them.
  • I used to get those and 'missing miles' where it wouldn't auto-resume, etc. I added a Speed sensor to the read wheel and haven't looked back.
