I thought this was an interesting race in that none of the young, physically fit type of couples made it to the end. TK and Rachel were the fittest of the final three, but they were by no means athletic types. I really have to give Ron and Don credit for tenacity and stamina. Those challenges are not easy!
I would have been okay with any of the final three winning. I did feel sorry for Ron and Christina, especially Christina, since she probably beat herself up a lot for not getting through the last challenge faster. Nick and Don were fortunate to be in third, I think, what with Don's age and Nick not being the sharpest knife in the drawer. In the end, I was glad not to be hating one couple and going "Aargh!" if they won.
