10 mile recovery

Why did this run hurt so much? ow ow ow ow ow. it was like I had never even run before. every step hurt forthe first 3 miles. it was like my muscles were frozen and they didn't want to wake up. I guess this pretty normal after a long run like last week's 23 miles. This was my first run with my new watch. it isn't as comfortable as the timex, but it sure works well. Here is the route. The GPS gives the weather, as well as all the hills I ran. It gives my heart rate graphed against speed. It is so much fun!
