Thank you, Pedal Wench. Maybe if I bump up my intervals to twice a week and then a few weeks before, try 3 times/wk, it will be enough. Really, right now, I'm interested in long-term fitness and being able to ride longer distances without killing myself... just a base fitness that will allow me to enjoy many hours in the saddle at a moderate pace. With this area where we're camping being so hilly, though, and absolutely stunning at that time of the year, I just want enough climbing ability to enjoy the rides without sacrificing my other goals. Headwinds we have in spades... intervals into headwinds are definitely do-able. Thanks again!!
