Running Man (Korean: 런닝맨) is a South Korean variety show; a part of SBS's Good Sunday lineup, along with K-pop Star 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.[2] 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.[3] Airing at the 5 pm 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 6:10 pm and airing against KBS2 Happy Sunday's 1 Night 2 Days Season 2 and MBC Sunday Night's I Am a Singer 2.
The MCs and guests were locked in a landmark during closed hours and
were required to leave before opening hours. In the first episode, they
were divided into two teams and raced to find the codes hidden within
the landmark that were required to unlock the main doors. With a total of 5 numbers, after one was found, a game was played to
determine which team would start first in the next race, and the losing
team received a punishment while the other team was given a head start.
After all the numbers were found by either of the teams, they approached
the main door and entered the code which they believed was correct. The
correct team was allowed to leave the landmark while the losing team
was required to complete a punishment inside the landmark.
