Running Countdown - S1.E490

This week, Heo Kyeong Hwan and Kang Han Na show up again as guests. With the joking over and done with, they each grab a random phone. Each phone has a different time allowance that will determine their fate. As soon as the race starts, the timer will run unless they stay in their safety zone. If they leave their safety zone, the timer resumes. Watch as they scramble to win more time to avoid elimination.
