My 3month old Forerunner 55 won't sync today with my 50minutes run. I was a overweight person and still are but having my stats always motivated me. Now I feel depressed today cause of this. My watch still show the data but the file don't work. I get error code 400 with file type is ok but the file have error. I was able to decode the file in Golang and see all my data. All the timestamps is in order etc I don't know what happen. From what I see why I can't decode it but not Garmin ?
I'm on Mac so some of the tool to fix it won't work. It's possible to fix the file somewhere on the web or I should just forget about it ? And the worst part it's from the 5k coach plan program and now this won't count
