The Biggest Loser S06E06 - Longest Challenge Ever

This week, the contestants are left in the dark - literally - during a wild baked goods temptation, with the winner gaining considerable power that could completely change the competition. Later, host Alison Sweeney wakes the contestants up to gather them for the challenge, which will last from sun up to sundown - the longest challenge in Biggest Loser history. One contestant struggles with a decision about whether to stay at the ranch or go home, and then an elimination round sends another contestant packing.
