The problem you're going to hit, Marty - is that you cannot actually attain the speed of light, in order to get on the treadmill to violate it. Mathematically, the energy required to hit the speed of light is infinite.
The only reason "light" can hit the speed is because it has no mass.
You have mass, therefore, you can never attain the speed of light.
And there's where your analogy falls down.
