After 1 month on injury couch and 2 days pain free, I decided to give it another try. Started program at beginning on 2/18/15. Mild knee pain started a few minutes after I finished entire run. I had a great run. But just a little disappointed about returned knee pain. I stretched before and after more than usual. I used my new running shoes. I avoided heel strike. Hoping for a complete healing so I can finish this darn c25k. I've never been more determined about anything. Staying positive.
