- No female Duel was held in Episode 2, after Tina was disqualified from the competition following the "Ring Toss" challenge for punching Beth.
- Beth and CT were disqualified from their respective "Push Me" Duels, after improperly unhooking the flag from the carabiner.
- CT was the first male player to retrieve 10 flags in the "Dine-N-Dash" challenge. However, he was disqualified for not grabbing a flag at the first pole, after host T.J. Lavin explained in the rules that failing to grab the first flag would result in a DQ. Therefore, the male player with the next highest amount of flags retrieved — Evan, was declared the prize winner by default.
- Wes did not participate in the "Dine-N-Dash" challenge in due to an uneven number of contestants on the two teams.
- The "Paddle Me" challenge in Episode 15 was designated as both a male and a female Duel day. The Kicker Car Audio System prize was awarded to both Jodi and Wes for this challenge. All other competitors were automatically nominated for the Duel. CT and Svetlana came in second place in this challenge, and earned the right to select the Duel they wanted to compete in — vs. Aneesa and Brad, respectively. (The contestant at the end of the selection process also had a chance to select the Duel game (albeit randomly) throughout the entire season.)
