Well, I don't know if any of you are still interested and I am about done with this subject myself. So I'll write this last note and then go back to my usual haunt in BF.

I have had technical trouble getting either of the Rouvy apps to run on my laptop. The Workouts app runs on my phone but with some technical peculiarities. I've had several email exchanges with their "technical support" and received three replies. All three notes were short and devoid of technical content, seemingly written by someone looking for a reason not to have to answer or by someone following a work directive "just look it up in our online tutorials and don't bother the programmers with questions". The second note asked a question that I had already answered in the note it was replying to. It was clear that whoever responded hadn't bothered to read my note. Today's one sentence reply was about as pertinent as telling me I need red tires. Very disappointing.

On the other hand, Zwift has worked marvelously so far. There is much I haven't explored yet.
