Hi, wondering if anyone can help - I have a FIT file which displays basic detail on my Garmin 810 (miles/time) but won;t display all the other recorded data (HR/cadence etc) - it also will not upload to the Garmin site and seemingly doesn't seem to register as an activity. However I can upload it to RidewithGPS and it displays all the correct data. I'm guessing the FIT file pixies have corrupted it (it displayed fine yesterday on the 810) overnight... Can anyone suggest how to fix the FIT file.
