If you can do 6 x 1600 at "5km pace" with a 600 jog in 3:00, then your true 5km pace should be much faster than that. That would be a killer workout at genuine 5km pace, and I seriously doubt most runners could do it. Even if you could, it's not worth the effort. It's definitely not the norm, nor a good idea, to try to run 9600m of volume at 5km pace. Doing 6 x mile at 10km pace, on the other hand, is a classic throwback workout. Long before the term "CV" got trendy, doing 6 x mile at 10km pace with a 400 jog was probably the single most common 10km workout in the US. Guys like Frank Shorter routinely did workouts like that.

I have a 6x1600 Track workout planned for this week. I am planning to do the repeats at 5K (5:20)pace and take a 600 Recovery (3 minutes or so). Would it be better to run the intervals slower at 10K(5:35) CV pace and take shorter recoveries(like 2 minutes/400 m)? I hope to finish the last repeat fast somewhere between 5K and mile pace (4:55-5:20) if I am feeling strong. I am currently training for a half in February and a marathon in March.
