Oh, hey, LCT, to address your question from Friday, Re: timing for those 6 workouts (i remembered on my own, amazing).
WO #1 (Max Steady) - this is one that I would consider doing about every other week. It's a progression run; I do these now, although I do them a little differently (I don't necessarily use 10K pace for them).
WO #2 (LR w/ "Movements"
- it says marathon prep and early to mid-season base conditioning. So, if you're going into winter maintenance phase, I'd start looking at adding this. You could do it every week, but alternating weeks is fine, too. Do it throughout winter, and into spring.
WO #3 (Hill Cycle) - like #1, it's year-round, Id do it once every 4 weeks to start, move up to one every 3 weeks later. Where I live, most of my running is similar to that, so hey. You could even do a hill-specific cycle for your training (as per Lydiard), and do this every other week for about 8-12 weeks.
WO #4 (2x7) - it says immediately prior to peak race season. This means right before going into the major race cycle, where your "A" race is. This workout is good for short to mid-distance runners. I don't know how good this will be for triathletes or longer distance people.
WO #5 (Half Time Fartlek) - transition from aerobic base to race or speed season. This one is good to help transition into higher intensity, anaerobic workouts, since it stresses both systems.
WO #6 (Mono Fartlek) - use rarely, I'd say mainly to judge fitness. It will help identify weaknesses that need to be addressed. Other than that, like the author says, it's a tough one, and to be used sparingly.
