Hi all! I am trying to start up my 80/20 Triathlon Training once again, and program comes with FIT files so that my watch will guide me through the workouts. My problem is that when I download the .FIT files to my MacBookPro and try to open them on my Mac, I get this message "There is no application set to open the document ________”, but the App Store has nothing that will help me. When I attempt to upload this to my Garmin Connect, I get "One of your files was not accepted by the system.", what do I do to upload these training plans and workouts??
