A 26.2 mile footrace that makes you very pumped up and excited but when you hit miles 19-21 you instantly regret signing up for but when you cross the finish line you get a major runners high
At first I regretted training for the marathon and I wanted to quit but when I finished it, I wanted to do it the next day.

Said of something where you have to work hard on something non-stop for a long time in a way that could be compared to a marathon.

A race attempted by a loarge assortment of idiots who lack the coordination or ability to use the basic skill of running in a real sport. Instead they decide to run for hours on end for no apparent reason. Marathons are oftenly described as "fun" by these morons for reasons unknown to the sane part of society. These retards also enjoy the loss of the ability to walk, run, move, fuck, for the 2 days following the Marathon.
Bob: "I'm running the boston Marathon "Jim"
Jim: "How long is it Bob"
Bob: "40 miles"
Jim: "Your a retard Jim"

a.k.a "Running a marathon" or "manathon"

When a group of five or more males masturbate one after another passing lubricant as the baton trying to beat previous records of time or contending groups' records.
J: Hey, do you want to go to the bars tonight?
E: That seems like a good idea, but that's in a while.
J: Should we pre-game?
E: I have a better "game," let's get the boys together and-
J and E: RUN A MARATHON!!!!!
(they high five)
J: I will get the lube!
E: I will forsake my self-respect!
