無限挑戰
During the early days of "1 Night 2 Days", the show was heavily compared with SBS's "Good Sunday"'s "Family Outing" and MBC's "Infinite Challenge", particularly because Noh Hong-chul was part of both "1 Night 2 Days" and "Infinite Challenge" (which aired on Sundays and Saturdays, respectively). However, the concept of the three shows is different. The concept of "1 Night 2 Days" is traveling on a trip with families and friends, while "Infinite Challenge" is a challenge-based variety program with 7 men competing in games.
