"Running Man (Korean: 런닝맨) is a South Korean variety show; a part of SBS's Good Sunday lineup, along with Kim Byung-man's Law of the Jungle 2. It was first aired on July 11, 2010. This show is classified as an "urban action variety"; a never-before-seen new genre of variety shows.[1] The MCs and guests complete missions in a landmark to win the race. It has garnered attention as being the come-back program for Yu Jae-suk, the main MC of the program, after leaving Good Sunday's Family Outing in February 2010.
Airing at the 5PM KST time slot for most of its run, Running Man switched to the second part of Good Sunday (which happened May 22 and May 29, 2011 with Kim Yu-na's Kiss and Cry but was quickly switched back due to low ratings) beginning May 6, 2012, airing after Kim Byung-man's Law of the Jungle 2 at 6:10PM and airing against KBS2 Happy Sunday's 1 Night 2 Days Season 2 and MBC Sunday Night's I Am a Singer 2."
