This week, it is the eight-year anniversary of Running Man. To commemorate such a wonderful day, the Running Man members are once again given missions. This time, it is related to the number “eight”. The members are divided into teams, and each team has a distinct mission. For these missions, they need to call in guests. The first 3 members who get all the 8s can move onto the finals. Who will gain victory? (Source: Viki) Special appearances by Hwasa, Moonbyul, Solar, Wheein (Mamamoo), Jang Do-Yeon, Shin Hye-sun, and Sung Dong-il
