1x817 - Running Man

The members dedicate a special race to veteran cameraman Kang Chan Hee, who has been with Running Man since its first episode. To thank him for 16 years of hard work, they compete in missions to earn darts and win him a collection of special gifts. Their final challenge pits them against a professional dart player, with every dart they earn improving their odds. Will the members overcome the pro and send Chief Kang home with all the prizes?
