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"
