a 4x400 meter race in which every time you get to the 400m mark you stop and eat a donut. you continue this until everybody but one person throws up, and you have a winner. Common with cross country and track runners, but not affiliated with the beer run.
Person 1: That was a fun donut run yesterday

Person 2: I feel bad for the person that has to clean that mess up

Get the donut run mug.
There are 4 men, two of them stand still while the other two with their dicks slicked up run at them as fast as they can and try to their dicks in the other persons ass.The first one to stick it in wins. The loser eats a handful of pubes.
Hey dude, that running donut game made my ass hurt.
