I'd like to be able to create interval workouts with erg mode power targets. Ideally, I'd like to be able to do this on the Edge 820, and in Garmin Connect.
It is possible to set a trainer target erg mode power on the 820, and display the target and actual power in data fields, but it's not something that can be programmed as part of an interval workout.
(Somebody has probably already suggested this but I certainly couldn't find it.)
