Trixoo, it was not as bad as I thought it would be but I will take another class and then make my decision. The instructor was great, the screen/video she showed was all outdoor roads so that was cool. But then she would flip back to some zone screen, we were supposed to be in zone 3 a couple of times, got lost on that since I don't have a HR monitor---not to mention that I wear glasses for distance so I couldn't read it! Lol
