Michigan today. Warm up, then mile on track, mile on grass, 1200 track, mile on grass, 800 track, mile grass, 400 track, mile grass. About 80 sec recovery. I heard 90, but usually it was 80. 4:40, 5:05, 3:25, 5:04, 2:18, 5:04, 64, 5:00. It hurt, but I kept through it. Last mile I wanted to go sub-5, but just missed it. Good day. The grass miles were supposed to be our recovery, but they weren't for me.
