I too would really like to have TrainerRoad workouts native in the Zwift workout interface. That would be sweet. Short of that support happening, using the Edge instead of the TrainerRoad app eliminates the concurrent Bluetooth connection issue of using two apps since it’s not an app, it’s a hardware device with ANT+ support that is already perfectly paired to my power meter, heart rate monitor, and trainer. I think it’s a seamless workaround instead of running both apps together (and the massive headaches involved in getting the right sensors paired to the right ones). I suppose having an ANT+ stick could do that too, but I already have my Edge and was already “dual-recording” on it because it’s my primary source-of-all-truth cycling computer.
