With their subscription model It’s understandable why they wouldn’t want to allow us to export workouts to our head units. You could basically get all of the workouts for your plans downloaded and then cancel.
However, the idea of mirroring the workouts from the iPhone app onto the Apple Watch seems like a no brainer to me. You would still be using the iPhone app as the source of your workouts, but the data would show on the wrist. They could even utilize the vibrate function to alert us of the 3-2-1 countdown before changing intervals.
For me this is definitely one of the best things about the Zwift companion app. In that case it’s not showing the targets on the watch, but it is using the watch to bring in HR data. No need to have TWO heart rate monitors on with Zwift in the way that TrainerRoad forces us.
Currently, the lack of watch support is my number one complaint with TrainerRoad and the more I think about it, the more I may have to reduce my five start rating down to four stars for this oversight.
