Call me crazy

yesterday when I got home from school, I decided to go for a run. It had been over a week since I had run at all, and a month or more since I had done anything this long. I ended up running 17 miles. It felt great except for the last two or three miles when my right knee started to hurt a little bit. It still hurts today. I hope I didn't really hurt it. I'll probably be able to still run on it, I'll just need to take it easy.
