The spin classes at my old club were geared much more to outdoor riders or could be modified to fit my needs. The ones I go to at my new gym are boring and geared for people doing aerobics on bikes. But, I do my own thing and the instructor is fine with it. I get more benefit from the interval workouts I do on my trainer 2-3x times a week, in addition to x country skiing. But, yes, like Indy says, it's always a ramp up when March comes.
