I don't know maybe I just like to punish myself. I was not a good "stick to your training schedule girl" today. I ran with a new friend and these hills were unreal. I am doing this run again next week and try for a better time. I did go backwards a few times up the hill so I could rest my calves! We ended up running 9 miles but really it felt like 20 miles. I am glad I brought my vanilla GU with me.... and of course the cell phone!
