Like running the hurdles. Work so hard, jump over every one, fast, high enough but no higher, because you can't afford to hang in the air. And then, when the race is over, you're dripping with sweat, either they beat you or you beat them ... and then a couple of guys come out and move the hurdles out of the way. Turns out they were nothing. All that work to jump over them, but now they're gone.
