It's time for a new game, and in this episode, the members get pumped up for a collaboration they are going to perform with an artist. Four mystery artists are here, and it's up to the cast to figure out who they are. The competition gets tough, and the members battle it out for their top pick.

The temporary artist and member teams need to get finalized, and through a series of wild games, each team competes for the right to exchange a current member or stay as they are. All eyes point to Kwang Soo, but he has no intentions of leaving Gummy's side. After each team has its members finalized, they meet up at their artist's studio and start their collaboration.

The fan-meet event continues. Every member showcases their individual or group performances on stage. They also put on their joint performances with the musicians. The stories of how they have prepared and practiced for months are also be revealed. One of the hottest idol group gives a surprise performance as well.

The artist collaboration performances are next! Gummy, Code Kunst, Nucksal, and SORAN take the stage with Running Man members to put the audience in awe. Next, the members shock everyone watching with an unbelievable group dance. And to finish off the fan-meet, they bring tears with Running Man's theme song that encapsulates the nine hard years of working together.

This week, Running Man celebrates its 500th episode. However, due to So Min's absence, they choose to keep their race simple. Lee Mi Joo from Lovelyz, Choi Yoo Jung from Weki Meki, and Park Cho Rong and Yoon Bo Mi from Apink join the show. They pair up with members and race for in-season delicacies known to rejuvenate one's health. Meanwhile, So Min sends a secret text message to the production team that later stuns all the members.

This week, Hoshi and Mingyu of SEVENTEEN, Nam Joo and Bo Mi of Apink, and two comedians, Kim Soo Yong and Nam Chang Hee, join the members to participate in Old Restaurant Race. They need to find old restaurants around Seoul and deduct as many years as possible from the sum of their age in order to win. Stay tuned to find out which team wins!
