My Garmins sync to both Connect and RWGPS automatically anyway.I've given up on it now and am reverting to Garmin Connect. Not a good, but at least it's available.
I gave up on MCL a while back but I do upload with that I just don' bother to tag and assign bike dataIf it comes back and you use Strava, you can use this nifty tool to upload all your rides rather than doing them manually.
