I just did the new 1 hour "CTS Climbing Power" workout tonight on my trainer and am exhausted. http://www.trainright.com/folders.asp?uid=19

You can't do this on rollers. This kind of a workout is worth more than several hours of mind-numbing spinning on rollers. Get a trainer and forget the rollers. You won't find any competitive cyclist that aren't doing power based workouts on trainers.

Just as an aside, to get only 18 responces to your poll today, shows how pathetic this new bike forum software is. Traffic must be way down.
