First 2 workout day

Today was my first 2 workout day. I did a 2000 yard swim (30X50 and a 500 cool-down). My second workout was suppose to be a 30 minute run, but I did 30 minutes on the elliptical instead, as I'm still not suppose to run. My knee is a little sore, but I won't say it is painful. I go back to the doctor next week. I hope I get the okay to start running again soon.
