The cast of "Run to the West" joins Running Man for a special race titled A World Where Only the Average Survives. In this unconventional competition, excelling or failing is equally dangerous. Only those who land squarely in the middle can win. Members get split into two balanced teams, and each mission will test their ability to stay perfectly average. The third-place finisher on each team claims the prize, while everyone else risks facing the penalty. Can they resist their competitive instincts and master the art of mediocrity?
