Sorry to bump this six months later but I wondered if TP ever resolved this? I switched from a power-based, to a pace-based training plan and I’ve gotten Garmin happy and running. However I was hoping to use Zwift as a “HUD” for running along (so I don’t have to stare at my watch when I’m on the treadmill). As far as I can tell, the normal duration based plans don’t seem to move from TP to Zwift (although, that could certainly be Zwift being buggy). I’ve started to manually build duration based workouts (as show above) and they seem to work fine, however if TP would do it “automagically” that would save the building time.
