Speed workout : 800s+ 400s

As I said warmed up 3k including drills( high knees, skipping, bouncing,straight legs), then did a planned workout that was 3 x 800s with 400s rest, and 2 x 400s with 200s rest. The splits were 3:22,3:20,3:19 for the 800s, 1:31,1:34 for the 400s. Felt pretty good during the workout, I was moving the legs "fast" and they did not feel fatigued. I was huffind and puffing in the last few repeats, but was feeling pretty good. Not bad splits given my current level of fitness, but way off compared to what I was doing 3-4 years ago. A lot of work to do here. Anyway, workouts are not meant to race them, but to stimulate the system you are trying to work on that day, so no biggies! Have a great humpday!
