INFINITE CHALLENGE

Season one of Infinite Challenge was called the 'Rashless Challenge' (무모한 도전). This season usually involved the members attempting to complete very extreme challenges, which seems near impossible.   There are 27 episodes aired during Season one.  The original members were come and gone, but MC Yoo, Hyung-don, and Hong-cheol survived to season 2.
