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.
