Thoughts

So, I went to get my flu shot two days ago and yesterday I felt horrible. I know they say that you aren't supposed to feel any different, but I disagree. All day I dreaded my run and almost didn't go. When I finally did, it was the best thing I could do. I felt great! As for today, I decided to make Fridays my non-running training day, just to keep it interesting. I did some weight training and spent some time on a nordic trainer. Another great day. As I train, I feel so good all the time. Why didn't I try this sooner?
