I have added a Garmin Edge 820 to my cockpit and now it is time to learn how to REALLY use it. I have been and will continue to play with customizing the screens to my liking. What I am not 100% sure about is the whole Workouts feature works exactly. I created the a Workout to fulfill this from my coach:

Start with a 10 minute warmup.
Then settle into a nice STEADY LOW Tempo 120-130 bpm at 78+ rpm.
During the ride, work in 4 X 10's at 150-155 bpm at 80+ rpm.
Allow a MINIMUM of 20 minutes back at LOW Tempo 120-128 bpm between each effort.

So I created this in Garmin Connect:

1. Is this how you would set it up?
2. Is it possible to export a Workout?
3. The most important question: Once I start a workout, since I made everything time based, will it automatically advance to the next step or do I have to press the Lap button to make it advance? I am hoping I have to press Lap.
