Over 25 years ago, I used to run. Not in marathons or anything, but with a group of friends. We used to meet at 6:00 am and run for an hour. I gave it up, not sure why. Since that time I have had knee surgery for a torn meniscus and just assumed that I could not run. Well yesterday on my walk I wanted to kick it up a notch so I decided to do a bit of running. One song walk, the next song run. I really enjoyed it. My knees are a little sore this morning, but I have cross trainer sneakers, so I think I will get a pair of running shoes and keep including the short runs in my outings. Anyone else do run walks?
