Race with my own Shadow

On your marks.....Get set......Go

I run, hard, harder, muster up all the strength I can, burn every ounce of energy my body could produce, but its there, running along with me, at the same pace. No matter what I do, I cant get rid of my sole opponent, its right besides me. I curse myself and run harder, but that doesnt help....

But according to physics, I am goin to win this race, by the distance of 1/3x10^11 mtrs, so there it is, the reason to celebrate, but wait, answer this questions to your own self first....

First: Is there any end to this race???? With no ribbons seen, the race seems to be endless, so I am not winning at all, no matter how hard I run. Its just impossible to get rid of him. Coz it is goin to be with me all the time, shall hide in the momentory darkness, but is gonna reappear as soon as there is a hint of light, so I accept it, and just wail in pain..

Secont: Whom do you symbolize your shadow with??? What are you running from??? i answer to myself.
