Running (treadmill) hills 30:00 [3] 2.04 mi (14:42 / mi)
shoes: Saucony Shadow 6000 8.5 # 3
Running, with some walking near the end. Treadmill set on "cross country 2" program, with speed varying between 3.5 (first 5 min to warm up) to 4.4, and incline from 0 to 9%, down to 3.8/walking for the last 7 or 8 min. When I tested my HR a couple of times during the steeper sections it was in the 135-145 range.
