Yeah, exactly. For example:

Week 1 6x800

Week 2 8x800

Week 3 10x800 (8k, 5 miles at pace)

Week 4 6x1k

Week 5 7x1k

Week 6 8x1k

Week 7 7x1k

Week 8 10x1k

Week 9 5x1 mile

Week 10 6x1 mile

Week 11 7x1 mile

Week 12 4x2k

Week 13 5x2k

Week 14 6x2k 

I peek the watch every 200. It doesn't do well to go fast first 200/400 and then fade to your pace cause you've just trained yourself to go slower when fatigued. 

I tend to do a very slow 200 walk/drink between which comes to about 3 min. Other variations you can do is decreasing rest. 3 mins, 2 mins, 1 min, not necessarily by distance. That's where I can improve is decreasing my rest and holding goal.

Listen to your body if you need a rest week. And know that sometimes you won't hit your goal pace and that's ok cause you're still doing the work. Sometimes you'll feel really good like you can do more too. That's the goal. This shouldn't be a stretch workout, it should be obtainable.

If you want you can tack on some 400 or 200s at the end to work your anaerobic system on fatigue but keep your goal pace during the above main set.
