Sunday--intervals today! Did our 1 mile warmup, then did 8 quarter-mile intervals, then a 1 mile cooldown. Did 1:42-1:49 for most of the 8, with a few of them over 1:50. Did a sub-9 warmup, and a 9:23 cooldown. Knee felt pretty OK, but I chose to stay on the outer loops of the track the whole time so the turns weren't so tight.
