I'm always hesitant to call myself a "runner" since that seems to imply that I run fast or something. I do run, however. I alternate running and doing the elliptical machine, so I usually run 2 or 3 times a week. I run between 3.5 and 5 miles regularly, and then I do a number of races a year ranging from 5k to 1/2 marathon. I've thought of doing a full marathon, since the 1/2 is not difficult for me, but I'm not convinced it's really good for the body, and my primary reason for running is health. At the end of the 1/2 marathon my feet are always just starting to hurt, and I wonder how they would feel if I ran the full 26 miles! I've never had a running injury, and at age 38 I don't really want to test fate. I'm pretty proud of myself as it is since I used to be a chubby person who thought 2 miles was a long run. Now I can run for a long time and feel quite good. It is definitely meditative for me as well. It's a natural anti-depressant!
