No it wasn't either!!!
It was the father and son.......Mike and Mel I think they are.
The cheerleaders came in last!
This is taken from the website:
Stepping onto the mat in last place, father and son Mel & Mike heard the dreaded words that they had been eliminated from the race. Mel said, "He [Mike] knew he was going to lose the race by calling me to get out [of the mud]. He cared more about me than the Race. And it felt good." Mike added, "My dad, he will never give up and that's why sometimes you have to give up for him."
