This week, guests Keum Sae Rok, Lee Ju Young, Park Cho Rong, and Kang Han Na couple up with Running Man members to race. Each couple will each get a card form a deck consisting of elements, punishments, and prizes. The combination of the two cards, held in possession by each team, gives a particular outcome. Each mission gives them a chance to switch cards with other couples. (thetvdb.com)
