What will happen if a stick and a beam of light is to race

Question

I don't know whether the question is asked before on not on this website as I can't found it anywhere so I have to ask. What will happen if a place a long stick with a length of a light year. Rather othe dimensions not matter just the sri k is a s long as a light year. Now I have placed a switch just in one end of the stick 1 cm apart. And the other end is on earth. Now my question is that what will happen if I push that stick and send a beam of light simultaneously toward thar stick who will win. The stick or the beam. I know the light will win but can you explain the phenomenon.
