Weather this morning was absolutely perfect. I was able to leave a little later because Amy works late tonight. The B on the side of the mountain was calling me so I headed up to it. I knew that this was going to be a punishing run but I figured I better take advantage of my mind willing to do it. The first 3 miles are a mostly flat with a slight climb then the next 3.5 are brutal - 1,500 foot elevation gain. There was one small section where walking would have been faster. Got to the B and followed the dirt road for about 1 mile then turned around and headed back home along the same route. On the way up, I kept my heart rate in the mid to upper 160's. It peaked at 176 during the steepest climbs. Heart rate stayed in the low 150's on the way down. I figured out what caused my left ankle to hurt. When I run downhill, I tend to keep my foot on the road a little too long. When doing this, my ankle hits the top of the shoe during the heel to toe transition. My ankle took a lot of pounding on Boston downhills. While this run hurt, it felt good to push myself a little. Mileage and time are estimates as I have been running Garminless for a while and I kept forgetting to restart my stopwatch after traffic lights. Total Time: 1:42:00 (7:51/mile) Avg HR: 157 |
