Speed Work Step Up

Because of work I could not do the speed workout Thursday night, so I figured I should still do it, so got up Friday morning and got it in. Was the 'step up' workout, 2 x 1/4 mile, 2 x 1/2 mile then 2 x 3/4 mile, with 1 mile warm up and cool down, and 2 minute recovery walks. 5.97 miles total in 57:15, average pace of 9:35, AHR of 160. 10:11 for the warm up mile, then 7:01 and 6:54 pace for the 1/4 mile repeats, 7:38 and 7:40 pace for the 1/2 mile repeats, and 8:04 and 8:05 pace for the 3/4 mile repeats. Finished with a cool down mile of 9:48. Legs are still tired, and I need to catch up on sleep at some point.
