While planned workouts download to both TPV and Garmin Edge computers, they do not sync, so that you have to use one or the other. While you can try to start both at the same time, it isn’t exact, and if you stop or pause, the two get completely out of sync, with different targets at different times. Additionally, because TPV dashboard stats are hard to see on an iPad while riding, I can see them much better on my Garmin head, and additionally my Garmin displays wattage targets as ranges, the cycling computer is by far the better option for doing planned wattage-targeted workouts. While I’d like to use TPV, it is all but useless for planned wattage-targeted workouts. If TPV could sync with the Garmin’s start / stop, I could use them both simultaneously.
