I have been Garmin user for many, many years. I don't recall ever having a corrupt .fit file on the Garmin side. I have had many, many issues with Zwift, however. So, during my ride today, first one with newest software update - 12.70. My battery went quickly, but I did not enter battery save mode. The unit lasted until the end of my ride, and I save as I always do. Upon attempt to sync via Express, I learned something was wrong. In looking at the history on the 820, I see the activity however it will not show me any details. In attempting to upload the file into Connect by selecting the file directly from the 820, I am told the file is not recognized!! I looked into the Garmin fitfilerepair tool, but I could not make anything work for me; trying different options I had read about. Thanks in advance for anything anyone may be able to do to enable me to upload this file to Connect, so I can get it over to Strava.
PS - just tried to attach the .fit file, however I am being told it is not an acceptable file format.
