hi Former Member
Garmin Connect import a tcx of 27.8MB failed and 25.7MB uploads
perhaps this is working on your GTC version...it does not on mine (version 3.6.5)
Garmin Training Centre file transfer to Garmin Connect
Open Training Center
Right click on activity or date range to be exported*
Select Export "date/time" or "Date range" (one week only at a time)
Save it to your computer "Desktop"
Open and sign into garmin connect
Click Menu icon
Select Activities
Click Import
Click Browse / Choose File button
Navigate to file saved on Desktop
Click on the saved file
Click Open
Click on Upload Activities from file
other GCT version could do this
Sending Data from Garmin Training Center to Garmin Connect
In looking to upload less data at once, I noticed something amazing.
Right click on activity or date range to be exported*
The “File” menu in Garmin Training Center also has an item called “Send ‘XYZ’ to Garmin Connect”.
I did that once for each year.
structure I use in GTC is this...and can only export weekly tcx...which are under 25MB
