4x400s

Part of a CrossFit Endurance workout:
Run 6 x 400m holding best possible pace.
Never slowing more than 3 sec from best interval.
2 min recoveries

I only did 4 rounds, as my calves were starting to flare up. I was slowing down a little, but I felt pretty good overall!

Times: 1:26, 1:23, 1:26, 1:29
