Just got a trainer and a question popped into my head after a couple of sessions on it. Do your trainer workouts last a shorter time than actually riding on the road? Usually, I'd last about 50km on the road usually in an hour 50 minutes, before I'm totally pooped out but on the trainer, I notice that I'd last maybe 25km in 45 minutes at most. Is that ok? Granted, I also notice that I recover faster from a trainer workout so I can do it everyday instead of having to take a day off every 2 days religiously but I wonder if that's going to do me any good. Anyone?
