Hi,
I have a Garmin Forerunner 305 and I would like to upload all my activities on Garmin Connect. I thus installed Garmin Express and added my device to the program, but once the synchronization starts, it never succeeds and instead I get an error message saying "there was an error during synchronization with Garmin Connect"...
I am a bit concerned about how to work this out. Last time I have added all my trainings (from the last two years) manually to the Garmin Connect, by exporting my data from Garmin Training Center into a .tcx file, but then I get one massive activity instead of all single trainings being counted as an individual activity (don't know if this is normal or not).
I can provide more information, I understand that this is a bit vague, but the error message really doesn't help finding out what the problem is...
