what are you talking about only doing z2/z3 efforts indoors over the winter??

Yes that is the case right now, but once January rolls around there will be z4/z5 efforts and that's where the trainer wins out for me...My race season starts first week of April so the build will begin January 1st...

For those complaining about trainer workouts and boredom. I have one answer...STRUCTURE...Trying to ride a trainer for 60mins, without a structured plan, is pure torture, but do a 15min warmup with some spin ups, 2x20min efforts (sub-treshold) with 3-5min recovery between, then some 2min efforts at 105%-110% of threshold and a 10-15min cooldown. You'll be verging on 90min and it really does not seem so bad. I find you start small on the trainer and work from there. Right now my sessions are about 70min and by the time January hits 90-120min will be the norm with 3hrs stints on the weekends. Last season I did 40hrs in January exclusively on the trainer and only the weekend 3hr sessions became torturous.
