16x 400 78-84, avg 81 with a 1 minute recovery jog, l ran 1 in 85, but the rest l hit 82 or 83, picking up the last one to 78, and one, my watch didn't start, but l ran the last 200 in 38, so it was about an 80 or there about. I was very relaxed and under control. The goal was 16x400s in 82 to 81 before l started.
