To celebrate the 10th anniversary of the show, the members participate in a mystery race where they have to find two thieves who stole CEO Big Nose's gold bars. The viewers participate in solving the mystery in real time. The result is announced through a live broadcast, allowing the members to have direct communication with the viewers. Will they successfully find the thieves? Stay tuned to find out!
This week, Profiler Pyo Chang Won and Detective Yoon Seok Ho guest star in the show to be part of the Running Man Thief Race 2. The members are nervous, since a real detective and a profiler are present to find the thieves hidden among them. Like the last Thief Race, each member is given a role, which brings more advantages. Will they be able to catch the thieves this time?
Running Man continues with the Old Restaurant Race. The years have added up, but ironically, the oldest team member gets an unexpected gift from a rival sympathetic member, turning the race into their favor. Next, Running Man welcomes guests Kim So Yeon, Lee Ji Ah, Eugene, and Ha Do Kwon from the show, 'The Penthouse', while Kwang Soo and Ji Hyo serve out their penalty from the Jeju Island Special. They fight once again to gain their way into the penthouse.
The Card Shark Association New Year's Party comes to an end. The last mission is a cutthroat game that will determine who gets to go home first. Meanwhile, the members regroup after a week.
