I've finally got everything set up and am ready to do my first Trainerroad workout.

I understand the concept(s) behind wanting to keep tire pressure and trainer tension constant from workout to workout.

What I don't understand (using Virtual Power) is how to know what gear to ride in. Since I am just using a speed/cadence sensor with Virtual Power, all of my results are going to come from how fast my tire is turning. Obviously, if I'm in my easiest gear, I'm going to look like a professional bike with a cadence of over 120 on all workouts. Consequently, if I'm on harder gears, my results are going to suffer as my rpms will be really low.

How do I reconcile this? Does the program tell you what gear to use?
