Their downfall came from making the wrong decision of who would complete a particularly physical roadblock challenge, and Zach and Rachel King now admit that they wish they could have chosen differently on The Amazing Race.

In a post-elimination interview with Reality TV World, the newlyweds, who were eliminated on leg nine of the race in Bali, admit that the roadblock Rachel did where she had to carry heavy amounts of water on her shoulders from the ocean and sprinkle it on a patch of sand was definitely what did them in-and they do wish they had been able to better determine what the task was going to entail before making the decision that she would complete it.

"I mean, we couldn't see what the Roadblock was because it was around the corner," Rachel said. "We were pretty much blind-guessing. And I heard 'salt,' so in my mind, I think I thought maybe it was cooking or something like that. In addition, we had been doing our best to go back and forth for Roadblocks, and Zach had done the last one or two. So, it was my turn to do it."

Zach also admits that having to watch his wife-the only woman who completed the task-struggle was also incredibly difficult for him.

"It was so heartbreaking to see. When we walked around that corner after we had chosen [her]--because we didn't know what is was and the clue was very vague-and at this point, we were switching on and off," he said. "And it was tough because we saw, as I walked around the corner, [Tyler Oakley] drenched in sweat. And then Kurt was there. And I knew these guys were, like, Kurt and Tyler are pretty-they can lift stuff!"

The couple also revealed that had they survived another leg, they believed they may have had a chance to overcome Brodie and Kurt, who just edged past them to claim the final spot and qualify for the next leg, especially since Kurt had used up all of his Roadblocks and they all would then begin to fall on Brodie's shoulders.

"we knew that luckily Kurt had used all his Roadblocks by that point and Iit, you know, Brodie isn't the best at puzzles and you saw with the kite, like tying the small knots and detail work-he's more about heavy lifting and the really physical challenges, which he's great at," Zach said. "So we were thinking, you know, if we had stayed in the Race past this episode, we would have that to help us, where we speed up generally during all the Roadblocks and the Detours. So we were hoping that if we stayed in it, Brodie [doing Roadblocks] would be to our advantage."
