Ok, I will take your word that it is not specific enough for what you need to accomplish, but I am not training for a specific goal. Rather I'm workng to in general iprove my fitness to where I am comfortable in a leisurely 45 miles on level ground, in April, with perhaps some light midwestern hills. Right now my goal is to work up to where I can break in my butt after a long cycling layoff, and be capable to start some outdoor hill training in April if not before. My intuition about this is that I should start by just pedaling, and I think a polarized "just pedaling" will give me a more effective workout than 30 minutes of just pedaling at 50 or 60 watts. I think my interpretation of 80/20 is practical for me, and is consistent with the goals as I shared in my previous post, and for these goals I think it is adequately specific.
