I run in "them thar hills". Thought that I ran more than 13 miles, but measured the course in the car. It was only eleven and took 2 hours and forty-five minutes. I am not at all trying to run very fast. When I fell like stopping and stretching, I do it. I walk up steep hills - and at other times as well. Isn't this what aerobic conditioning is supposed to be like? My heart rate is about 120.
