One week ago I completed my first 100 km ultrarun. Unfortunately my Garmin Fenix 6 gave an error while uploading. Manually connecting the watch and uploading it did not work. I tried to upload the .fit file to Strava and this worked. Also Stryd found no problem accepting the file. Garmin Support suggested I try to repair the .fit file. Also this did not work. Maybe the file is to big (about 4 mb) or I had to many breaks in the run. (I paused the run every hour since it was a Backyard event) Hopefully is there anyone on this forum who had had the similar problem and knows the solution. To lose a training run is obviously not a problem, but to have a 100 km ultra not in the Garmin stats is not so nice. Thanks in advance!
