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.
