Surprised at how many use the KK and TrainerRoad.
I use a Cyclops Super Magneto with TrainerRoad for structured workouts, intervals, etc. And Tacx Galaxia Rollers for recovery or Z1/Z2 rides. Fortunately I've been able to get outside on average once per week in between weather but still using the trainer for most rides right now. Like some others I may use the trainer during the season for some structure, the terrain where I live makes it really hard to control (lots of short ups and downs)
