I'm not really sure what it is about 4 miles for me. These runs either go very well or very badly. It can really go either way, but mostly the later.
Tonight however, I had a fantastic 4 mile run. I had an amazing pace going and I felt great. I felt like I could have gone forever at that pace. I love when I settle into that. It's comforting and nothing can stop you. Which may include the treatorous winds we dealt with for a bit. I think I'd like to say that this was the first of many brilliant 4 mile runs I have ahead of me in weeks ahead. We were on a great path and I think it did something for me.
