Unllike others, I don't run for enjoyment. My motivation is to get back in shape for backpacking now that my weekends are free. I've decided to walk with a small pack. This allows me to use my karma, but it takes a lot longer. I average about 4 miles an hour and and like to get in 6 to 8 miles a walk.The time spent is a little more than I wanted but its better than running in silence.
