While not official, there is a script posted to the Garmin forums which allows for bulk download/export of FIT/TCX/etc data.

Here's a version I've improved a little + adding export of "wellness" data. This thread was a good reminder to push my changes out to github. https://github.com/bbbbbr/garmin-connect-bulk-export

Edit, add:

Lastly, while the UI has some quirks and it doesn't have a social component, My Tourbook is a solid offline, cross-platform alternative to the online fitness repositories. There is something to be said for having complete control over your data (make sure to do backups). http://mytourbook.sourceforge.net/mytourbook/

Ok, so things haven't really changed that much. They don't actively prevent you from getting the data, but they don't make it easy either.
