Learn how SMILING can improve how you feel on a run...

As I was running along the Trolley Trail during the last 2 miles of a 10 mile run, I reached a point where I didn't feel so good. The old hip was screaming, the calf was complaining and I felt overall fatigued. And that's when it happened, I came across something that made me smile. And suddenly I felt amazing. No aches, no pains and no fatigue!

I did a little digging and found a scientific reason for this phenomenon. Smiling releases pleasure hormones called endorphins, natural painkillers and antidepressant hormones such as serotonin. It also helps decrease stress. 

So next time you are feeling not so good during a run (or any time actually)...try a SMILE. It works like magic! Maybe this is why running with friends is better - they can make you smile on a run.
