Yes, but my poor old knees, stripped of cartilage as they are, do not respond well to running on pavement. The bit of padding on a treadmill allows me to exercise. Hurrah for treadmills!
Well yes. I ran for a very short period a few years ago, in a gym for a period and then when the summer came I moved onto Marley Park.
Second trip out I banjaxed my achilles tendon areas and decided there and then that running was for poofs and second hand car dealers.
