When syncig courses, calendar or workouts from Garmin Connect to Garmin Forerunner 920xt, it seems, that Garmin Connect refuses to send activities unless Garmin Connect Plugin and Garmin Express is installed on the PC.
Or am I doing something wrong?
My idea is, that on any PC (without Garmin Connect Plugin installed) I will create a workout and send it to my device using WiFi tethering of my mobile phone.
