FYI, it's not hard to create your own workouts -- they're just in simple text file (ASCII) format. If you check out a book like "The Time-Crunched Cyclist ..." from the library (or buy it), you can take a few minutes to translate a whole training program, e.g.
Time-Crunched Training Program (TCTP), into a series of ErgDB workouts to be used in GoldenCheetah.
A sample is shown below, which I translated from the book into ErgDB format. I used percentage of FTP vs. absolute wattage, to make it more useful. Save as *.erg and import into GoldenCheetah via Tools/Import Workouts...
