A phenomenon amongst particularly sadistic runners. When it comes to time leave a party and the runner is too intoxicated to drive, he/she has their friends drop them off at their house so they can run to their car in the morning. Can represent a distance from 1 mile to 26.2.
Ben: Man, can you drive me home? I'm way too wasted to drive.
Mike: How are you going to get your car man?
Ben: I'll need to exercise off this hangover anyway, I'll just go for the morning after marathon.
