Players from each team have to transfer hand-carved wooden giraffes across a lake, to one of 15 cages that contains an identical twin giraffe. There are numerous giraffes on the shore across the lake that are in different shapes and sizes, and before advancing across the lake, each player has to randomly uncover one of 15 cages at the start of the course that are covered with white tarps, then memorize the details of the caged wood-carved giraffe inside, then swim across the lake to find the identical matching twin, with a key that will unlock a player's designated cage at the start of the course. Each player will have a 30-minute time limit, and the team that completes the challenge in the fastest average time wins.

The Finalists brave the elements and extreme altitude as they race through the mountains of Argentina with a million dollars in prize money at stake. At the finish line, TJ has one last dirty trick up his sleeve

Bananas and Wes' alliance comes to a crossroads as players realize that they may not have much longer to earn a Red Skull to make it into the finals. Players must compete in TJ's favorite game of each season: trivia.

Players from each team have to fill up a series of team-designated glass bottles with grape juice on one side of a course, by transferring handfuls of grapes from the bed of a classic truck to a wine tub, then smashing the grapes, which will send juice through a spigot, where players have to transfer the juice with their mouths to the glass bottles. The team that transfers the most juice into their designated bottles within 30 minutes wins.

Players have to advance on a series of five platforms, with trampolines located in between. Each platform decreases in size as each team tries to advance to the end. To start, one player at a time will jump from a trampoline to a platform, without their hands or arms coming in contact with the platform, which would result in a player having to start over. Once players from a team have made their way to the final platform, their team time will stop when they hold their pose for three seconds. The team that advances o the last platform in the fastest time wins. Note: Aneesa was prohibited from participating in this challenge due to a knee injury. As a result, the Good Guys were forced to sit out one player (Paula) in order to even out the teams.

Teams have to race on a 300-yard railroad track on a "hand car." To start, two players per team will pump their hand car from one end of the track to the other and pick one teammate, then race back to the opposite end of the tracks and pick up another teammate, and the process will continue, until each team picks up all of their teammates, and reaches the stop zone. A hand car must come to a complete stop within the stopping zone before a teammate can climb into the hand car, and each player is required to pump the hand car least once throughout the challenge. The first team to pick up all of their teammates and reach the stop zone wins. Note: Since the Bad Asses had one more player than the Good Guys, one player from the Bad Asses team (Jenn) sat out this challenge.

Players from each team are asked a series of ten trivia questions regarding information related to the Inferno 3 challenge. One girl from each team is designated by the opposing team as the "Captain," and will be strapped into an African throne, and be connected to designated electric shock boxes. T. J. Lavin will ask the remaining players from each team trivia questions. Each player will write down an answer on an oversize card, and if a player is correct, he/she accumulates points for their team, but if an answer is wrong, the captain will get "zapped." The team that accumulates the most points wins, and a team wins if the captain from the opposing team decide that she can no longer handle the shocks.

Players from each team have to climb up a cargo net that is hanging from a platform above water, retrieve one team flag, then unhook a rope in order to swing themselves toward another cargo net and retrieve another flag. The process continues until a player retrieves four flags. If a player falls off the rope or the net into water, he/she will be imposed a time of 15 minutes. Each player will have a 15-minute time limit to retrieve four flags, and the team that completes the challenge in the fastest average time wins. Note: Tonya received a medical exemption from this challenge due to dehydration, and did not participate.

Teams compete in a 50-yard dash, using dog sleds. The challenge is played in male/female pairs, with each pair dragging sleds with a male/female pair from the opposite team sitting on the sleds. The team that completes the challenge in the fastest average time wins. Note: Two girls from the Good Guys team (Paula and Susie) were required to compete twice, while two girls from the Bad Asses team (Aneesa and Jenn) were forced to sit out the challenge.

The male players on each team are positioned on opposite fishing boats, with each boat containing a deep-sea fishing pole. One girl per team will be in the water, attached to the ends of the fishing poles. Each girl will have 30 seconds to swim as far away as possible from the boats, then T. J. Lavin will signal one guy from each team to pick up the fishing poles, and try to reel in their female teammate out of the water. The process continues, until the team whose male players reel in all of their female teammates out of the water in the fastest average time wins.
