My view is that the lack of recovery is the big issue. Even when out on the road, if I do a two-hour workout at a steady tempo it is more challenging than two hours with the same average heartrate, but including peaks and troughs.
Riding a trainer is like riding uphill, but the hill doesn't end until the ride does..... I find the best way to use a trainer is to in insert gaps into the ride, for example 9 minutes on, 1 minute off, then repeat. The one minute off, allows for the recovery you normally get on the road, but it's not a long enough gap that you cool down.
