I like going by distance, not time. I find I push myself harder because I know then I'll get done a few seconds sooner. It's also easier to see a signpost or a building than it is to read little itty bitty numbers when your legs feel like they're being dynamited, your eyes are bleeding, and your heart and lungs feel like they're going to climb up out of your throat and beat you about the head for abusing them so badly.
One KM is good.
One mile is utter hell.
