impossible to import
What are you trying to import? An activity? A course?
Zip then attach it here so we can see what is wrong.
Thank you, it is a running activity
Was a Garmin device used? This looks like a workout from Training Peaks app.
Exactly, I did it!
I did export the FIT file to my Garmin device simply using "Sync" from the App Garmin Connect, much simpler
Thank you very much
