Keeping it simple
So, allow me to simplify your life and alleviate you from any further frustration. :) Here follows my humble philosophy:
Organize your week around 2 interval sessions and 1 longer distance workout at "race intensity". Preferably use 1 interval session in zone 3 and the other one in zone 5. For obvious reasons, the distance workout must be in and around zone 3-4. After you have placed these key sessions and planned for adequate recovery before and after them - fill in with long, easy to medium intensity rides. I would also recommend 2-3 strength sessions per week, time permitting. If you are experienced enough to feel when you need to rest and recover, then don't bother scheduling a low week. If not, plan 1 easy week every 4 weeks. Train about half the volume of your normal week.
When / if you need to reduce volume (racing season) - keep the key sessions (intervals and distance workout), just reduce the longer endurance rides.
I also believe in keeping the key sessions all year long, if possible. So, that's it. Simple, yeah? Now all you have to do is get out there and put in the time. Oh, and make sure you focus on quality, quality, quality.
Now I got to get back to watching "Underworld". Ah, mindless violence. Great after a hard day.
