S01E486: Running Martial Arts School: Trade the Cards

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.
