In the exclusive clip above, the final eight competitors—Sarah Burkett, Patrick “Freight Train” Hargan, Scott Henry, Iraida Mujica, Liz “Knuckles” Nichols, Cyril “Zeus” Ontai III, Swifty Sanders, and Merryl Tengesdal—remaining in the hunt for the $200,000 grand prize and the champion title compete in this week’s Individual Challenge. In pairs, they fulfill the role as window-washers, with one person scaling down a building cleaning along the way, while their partner guides them below. The job, however, is easier said than done. Several competitors struggle to stay on task, with Freight Train’s fatigue beginning to set in and Swifty spinning out of control. It’s a do-or-die performance, as the pair who finishes in last assumingly will go into this week’s Overtime Challenge, where one of them will be eliminated. And with the final challenge getting closer and closer in sight, every wipe could be the difference between $200,000 and punching out for good. Check out the clip above and watch Tough as Nails at 8 p.m. Wednesdays on CBS. Next, here’s why Michael “Eyebrows” Guerriero left Tough as Nails season 2, according to host and creator Phil Keoghan.
