I ran on the Pittman wash this morning. I was running uphill into a headwind on the way out, and downhill with a tailwind on the way back. I tried to keep my HR in the low 130's on the way out, and I hit my turnaround in 42:00. On the way back I ran 4 x 800 with about 400m rest after the first two, and about 800m rest after the third. During the 800's I tried to keep my HR right around 170 and I ended up with splits of 2:36, 2:36, 2:42, 2:35. The third repeat was slower because it was during a half mile that has 7 sharp turns, a steep downhill (with a sharp turn at the bottom so you can't use the downhill effectively) and a steep uphill. The fourth repeat had more downhill than the others and utilized the wind better, so it should have been faster, but I accidentally let the HR drop into the mid 160's during this repeat (probably daydreaming) and I finished close to where I was at during the first two repeats. Total time for 10 miles was 1:15:05 (33:05 second half).
