Trainer for base building?
I am a newbie and the problem I'm faced with is living with all hills around me. I've posted elsewhere about my problem of getting base miles in to increase my ability to ride for long durations. No matter which way I go from my home, I need to leave enough in the tank to make my 2.5 mile climb back to my house, not a fun matter when my condition is not great.
The problem I have is time. I can get out for a 30-60 minute ride for 10-15 miles 4x/week and hit the hills (I have no choice where I live). What I would like to do is drive my bike to flatland to ride long distance to build my base but I just do NOT have time with work and three kids to do that (one of whom is in somewhat poor health demanding more time from us). I'd like to get up to 50 mile rides. Does anyone use a trainer (ie Kurt Kinetic) for base building? I can get on that after kiddies are asleep about 9pm and put time in, or before sunup. Is that a viable strategy?
Joe Friel says in his training bible that for beginning cyclists base building and long duration, low intensity rides are most beneficial, but a few pages later says the ability to clear lactate is best done by high intensity shorter workouts. I certainly get that on these hills and while my climbing is getting better, after 15 miles my body starts to feel real cramped since I'm not used to being on the bike that long. The LBS said just ride the hills, forget the rest but I don't have a good base yet (at least I don't think I do).
Any advice is appreciated. Again, the issue for me is time to ride during daylight. Night time is out, I'll get wasted by a truck out here in the country.
