6 Mile Tempo Run

Did a tempo run this morning, 4 miles @9:40 with 1 mile warmup/cooldown on the agenda. Ran a bit faster, but it was cool and comfortable out. 6 miles in 57:06 overall, 9:31 pace, splits of 10:14 (warmup), 9:25, 9:24, 9:19, 8:57 and 9:44 (a bit of a cool down). AHR was 165 overall. Was in the low 50s, felt pretty good.
