Training Center allows the user to create repeat workout steps with rest steps whereas Garmin Connect does not.
Also Training Center allows the user to include a short description of the workout step whereas Garmin Connect does not.
For example, my indoor cycling warm-up includes 30s standing and 30s seated x 5. This was easy to create in TC but it is impossible to create in Garmin Connect.
I've attached the workout for your reference. It would be great if Garmin could change the Garmin Connect workout utility to allow for this complexity which is not unusual for workouts. It would make it a lot more useful. In the mean time, I can import the workouts from TC into my Edge 810.
Kind regards,
Albert:(
