No, none of that confuses me at all. I get the "big picture" just fine; I can write an annual outline, I understand periodization, mesocycles, etc. I can be honest with myself about where I'm lacking and therefore what needs to be addressed. I can put together what areas of fitness need to be worked on for a particular day, what days of the week things should go in, and have a very successful Fall strength training program in the gym (I can leg press more than 3 times my bodyweight). It's just really been the two parameters of an interval training workout: sets, and duration that are tripping me up. I'm not a big fan of things that are so "organic" as determining those, my brain isn't wired so good for it. I suppose it'll take time and experience to be good at determining those factors, but in the meantime I don't want to screw myself up and either end up having a crappy racing season where despite my best efforts I'm falling off the back all the time, or end up in overtraining syndrome, or worse, injured.
