I was attempting to run a 7 mi tempo run and all was well until about the 6th mile then my left knee started to give me pain. Luckily, this was a cool down mile but it kept getting worse until I was hobbling at the end. I got home and started to RICE the injury. I'm supposed to run a long run tomorrow for 12 miles. We'll see how that goes. Any major pain and I'll be back to the couch.
