Running

It begins with d²x/dt²
A slow crescendo of soles against pavement
Souls against the pavement

Air becomes viscous
Resistance
Fd = -0.5ρν²ACd
Exhilarating

The pain begins to fill my lungs
Needles stab my throat
Needles make my knees weak
But still I run

The finish line isn't far ahead
The finish isn't far
I'm so close now
To the end

Most people walk to their destination
But I must run
