First up "Cut Me Some Slack" eliminates one competitor and "Air Mail" ensures someone is sent home marked fragile. Boomer takes the three that remain and prepares them for the secret final challenge where they'll meet Caz.

In the quest for this week's Ultimate Adrenalite, Boomer's "Commando" forces one competitor to make a splash while "Heavily Armed" turns out to be a chance for competitors to put their best foot forward.

"Cargo" shows even a simple looking challenge can be difficult and "Resistance is Futile" proves The Adrenaline Project is about brains as much as brawn.

Base Camp training runs one competitor aground and eliminates them with "Dry Dock". "Hang Man" leaves the second competitor out to dry leaving us with our final three to face the final extreme challenge.

The hunt for the Ultimate Adrenalite leads to a long walk home for one competitor in "The Trek" while "Search and Rescue" goes on to prove another competitor can't be saved from elimination.

"Gone-dola Crazy" eliminates the first competitor and "Soup's On", a new twist on fine dining, eliminates our second competitor. The remaining three move on to the final event in hopes of becoming The Ultimate Adrenalite.

"Start Your Engines" causes one of our competitors to stall while "Snow Storm" freezes yet another in place at Base Camp. That leaves our final three to face the final extreme challenge.

"The Drawbridge" is down, but one competitor will not make it across to join the four that are heading out to the field. That's where they'll learn isn't always fair with "Pop Up."

"Fruit Cocktail" may sound sweet but it brings one of the competitors to a bitter end. Four competitors are whittled down to three by the "Triathlon", moving on to the final extreme challenge.

"The World Turned Upside Down" drops our first competitor out of the running. The remaining competitors hope to hit the stratosphere, but "Space Case" brings one crashing back to earth.
