You don't know how hard it gets when I'm alone I'm all alone in my head You don't know how tight to start is When you run, when you run all night When you run, when you run When you run, when you run You don't know how hard it gets when I'm alone I'm all alone in my head You don't know how tight to start is When you run, when you run, when you run all night When you run, when you run When you run, when you run
