A solid track session 3x800m 1x400, 4x200m

Today was a good track session where I worked on improving both aerobic and anaerobic systems. I started with 1x800 @ 2:18, 2:23, 2:10. Then a 400m @ 57 seconds. 4x200m @ 28,26,26,25. I finished with a light weight training session. I noticed that I was able to jump into a second gear on the last 50 meters of my 200m. I am starting to feel like I may have a 1:52 800m in my legs.
