Running at 6 in the morning is the perfect time to run! It's so nice starting out in the dark and finishing while the sun is still rising. It makes such a difference in my day too. I went out and ran my 5 miles all around home. I felt good. I wasn't concerned about going fast. I don't need to be fast. Right now, I'm just concentrating on finishing.
"Run with your heart instead of your mind. When you run with your mind you think of what you can and can't do, but when you run with your heart, you forget about what you can't do and just go out and do it."
