In reply to Shaunhaynes99:
I did a run both Sat and Sun and it sync'd to Garmin Connect ( and then on to Strava ) ok.
Where is it that you are looking and see it only "half synced" - is that Garmin Connect or Strava or somewhere else ?
How do you sync ? Is it an older watch and via a USB cable, or a newer one that connects to your phone via bluetooth, then over wifi/cellular from your phone to Garmin ?
If it's a newer one, have you tried re-syncing ( either from the phone or the watch ) ?
