In this week's episode, Running Man races to celebrate Hangeul Day in beautiful Cheongdo, a region known for its persimmons. Mina from gugudan, actress Park Yu Na, singer Hwang Chi Yeul, and global superstar Tiffany appear as guests. They team up with the members and compete in a series of Hangeul word-based games for persimmon badges. The member with the most badges gets their handwriting made into a free downloadable font!
