The Marathon is the fifth official mixtape by American rapper Nipsey Hussle. It was released on December 21, 2010 for free legal download and for download on iTunes. The mixtape was released by All Money In Records.

He released the mixtape around the time he was trying to get out of his record deal with Epic Records so he could release his debut album South Central State of Mind independently. The mixtape's theme is a "declaration of independence from the confines of the traditional music biz that forced him to endure over two years worth of delayed celebration for the still-pending release of his formal debut, South Central State of Mind."

The first single from the album is "Keys to the City". The official music video was released June 6, 2011 on Vimeo and was directed by Dan "The Man" Melamid, who also directed the video for Nipsey Hussle's 2009 single, "Hussle In The House". The song was released for retail sale on September 2, 2013.

On the first leak off the mixtape, "Mr. Untouchable," Nipsey raps a bar that says: "High 'til we die, so it's muthafucc a Detox" [sic] which Nipsey in a interview with Vibe, stated it was not a diss line to West Coast rapper/producer Dr. Dre and his third studio album Detox. He also maintained the diss was "...nothin’ personal. I ain’t never really reached out to Dre, or Dre ain’t never really reached out to me, so it ain’t a shot against him, it’s just, my focus is on what I’m doing now."

XXL made the mixtape the 49th best mixtape of 2010 and praised Nipsey's ability to bring back an earlier era of West coast hip hop music.
