(immediately following 30 minute intense lift with nor rest). This is a rough estimate of what I did. I did 2000m @ 2:00 (barely under) and had nothing left. Finished about 200 meters more and stopped. Second round couldn't even break 2200 (more like 2170 or so) in 10 minutes. Was mostly a 2:03 / 2:04 pace. Hard lift.
