8x400m and 2x200m and some light weight training

I was surprised that I was able to do this workout today after a huge week of training. I am planning on racing the 1500m on Friday so I wanted to get a quality workout in today. I ended up doing 8x400m with 200m jog rest and 400m jog rest after 4 intervals. My times were 63,63,60,61,60,61,60,59 and finished with 2x200m @ 29,28 seconds. I did not feel that I was straining much during this session. 60sec/400m pace is starting to feel much more relaxed.
