Didn't feel too good today. I've been having breathing problems so running is quite tough when you don't get enough oxygen in your system. In addition my shins didn't feel all too good. Did a 400 at 75 pace then did 1600 at 5:00 pace, 1200 in 3:40, 800 in 2:18, and 400 in 67. First 400 ryan told us to go that pace.
