Soldato
I tried a few of them when Zwift changed its price and whilst I cancelled, when it comes round in May, I'll probably just renew Zwift for another year as to me it still is the best. I tried MyWhoosh, but it crashed about a mile into a ride, so that's off the list. I liked Rouvy for the real world rides that you can do and the pace partners it would drop in based on your current pace. I think they have workouts too, but I don't know Rouvy works for a long 2 or 3 hour free ride, where Zwift works really well.
