I tried Rouvy one time, seemed like no one was on it. Any other good alternatives?
Take your bike off the trainer, go outside.
Wow, what a clever reply.
you’re welcome
With community like Zwift you don’t have any alternatives.
Rouvy, Kinomap, Bkool simulator or from Tacx are solo pain apps 
Instead of zwifting you could sit on the couch and eat a bunch of nachos
What about BTR, anyone have success with that one?
I do like Rouvy as well, a lot of courses and video’s
The thing it is missing is the racing, this is why i will stay on zwift.
There is no draft in Rouvy and not a lot of people in the races.
I do love Zwift, i am also interested to see how Veloton turns out.
