I have read all of your posts and it sounds like your training bike is better suited to your riding style. I would venture a guess that if you timed a 20 mile course and rode both bikes as fast as you can you would have a better time on the trainer. You seem more efficient with it and probably expend less energy riding it. If that turns out to be the case, if I was you, I would ditch the so called long distance bike since your are using more energy not less on it.
