Since Garmin Training Center for Mac and Windows has been discontinued, we encourage everyone to move important activities from Garmin Training Center to our growing online community Garmin Connect, which is our full featured web analysis software that continues to add new and exciting features. Both PC and Mac users have the ability to manually upload multiple activities from Training Center to a Garmin Connect account.
*Up to one week worth of data can be exported at one time. However, uploading one activity at a time is recommended for the best possibility of a successful upload.
The file should now be available to view in Garmin Connect. Issues may occur when uploading to Garmin Connect due to file size limitation or if data from Training Center is corrupted.
