Runner's High

I believe they call it the runner's high:
The feeling of pain, numbness and exhilaration altogether.

Numbness in your legs
Pain in your chest
Exhilaration coursing entirely through your veins.

You start out realising
That every step out requires another step home.

After a while,
It matters no more.
You are pushing on without thinking of the journey back.

And you go further and further.
And you explore new uncharted routes.
And your sweat dries, dehydrating.
And you wonder if your delirium is heat stroke.
And you soon similarly do not care.

All that matters is the now.
And now, you are tremendously joyous.

That, I believe, is the runner's high.
