Despite finishing first on the last leg of the competition, Peter Harsch and Sarah Reinertsen got lost in Kuwait and found themselves on the border of Iraq, putting them right out of the running.

"'The Amazing Race' is the hardest thing I've had to do, mentally and physically," Peter told CTV.ca

The "Iron Man" team drove in circles desperately trying to find their final detour challenge at the Kuwait Camel Racing Club. When they gave up and tried to find a different detour challenge they inadvertently headed to the wrong side of the country. By the time they finally arrived at their destination, night had fallen in the desert, and all the other teams had finished the race.

Being so far behind, they were told to skip the task altogether and to go directly to the pit stop, where host Phil Keoghan informed them they were eliminated.

Sarah, who has an artificial leg, and Peter, who is a clinical prosthetist, had hoped to prove that disability would not hinder their chances to win. In the end it was a stumble in their teamwork and communication that foiled their chances.

"The Amazing Race" (Sundays on CTV) began with 12 teams of two racing around the globe for the prize of US $1 million. The teams never know what's coming next or what they will face once they arrive at each new destination.

CTV.ca talked to Peter and Sarah about how "The Amazing Race" stacks up to the Iron Man competition and what the race ended up doing to their long-time friendship.

CTV.ca: What was more challenging, the Amazing Race or the Iron Man?

Peter: "The Amazing Race," by far. With the Iron Man, you can plan for it. You're prepared for the road ahead. "The Amazing Race" is the exact opposite. You're not eating well, you're not sleeping, you don't know where you are going to be one minute to the next, and then you're under a lot of stress. "The Amazing Race" is the hardest thing I've had to do, mentally and physically.

CTV.ca: How did it feel to go from the front of the pack to dead last?

Peter: It sucked! It was frustrating because there's a team like Alabama, that just kind of walks through this, moseying on, relying on other team members. It was kind of a let down.

Sarah: It was terrible. We knew in our hearts that we should be top three.

CTV.ca: What would you have done differently?

Peter: I think if we made a left turn out of the fast forward, we wouldn't have ended up at the border of Iraq.

CTV.ca: Do you think your team proved that having a disability didn't slow you down?

Sarah: It was hard for me for sure, but we never let that get in our way. We constantly pushed the envelope, we ran, we crawled, we did whatever we had to in order to get to that mat as quickly as we could.

CTV.ca: Sarah, What kind of reaction did your prosthetic leg get in different countries?

Sarah: In India I remember walking down the street and the entire block, hundreds of people, sort of stopped and just stared at me. I've been stared at my entire life and that was overwhelming.

CTV.ca: In this last leg of the race, at the Kuwait Towers, other teams were wondering why your team decided to have Sarah do the climbing challenge instead of Peter. How did you team decide you would do what?

Sarah: We decided that for some challenges, Peter had to do it. Some of those things had nothing to do with me missing a leg, like eating challenges. I have a weak stomach, and I couldn't have eaten those fish eyes.

CTV.ca: What was your most memorable experiences?

Sarah: For me it was climbing the Great Wall of China. I will forever want to bottle that moment for the rest of my life.

Peter: Probably my most memorable experience wasn't even shown. After we finished in second place in Vietnam, the following day we took this boat and when it was racing across the ocean it was stunningly beautiful.

CTV.ca: What did you learn about each other during the competition?

Peter: The race really confirmed a lot of what I already knew about Sarah. She's very strong and not afraid of anything.

Sarah: One of the things I learned about Peter is that he is incredibly strong and pulled us along in a way that they really didn't show on camera. But I also learned that Peter has a tough time being mindful. He was so focused on winning that he wasn't mindful of how he treated or talked to people.

CTV.ca: What is your relationship like now?

Peter: Sarah and I have been friends now for years. We're going to have to work on a lot of stuff. The race definitely broke down our friendship and exposed a lot of things. Now we need to rebuild and restore our friendship and the things we had before.

CTV.ca: What team are you cheering for to win?

Peter: I'm cheering for the Cho brothers, I like them, they are really funny guys.

Sarah: Well you know I think the Barbies are doing a very strong, aggressive race. It would be great to see two women in the final three.

CTV.ca: Anything you would like to say to your fans in Canada?

Peter: Canadians are awesome. When we were begging for some money in two different places in the world, Canadian tourists always gave us some money to help us out. A lot of the Americans we asked never gave us anything.

Sarah: I echo Peter's sentiments. In the sport of triathlons, a lot of the athletes I look up to come from Canada, I know Peter Reid, Lisa Bentley. There's a lot of great triathletes, coming out of Canada.
