Standing among an Indy 500 winner, retired NBA All-Stars, X-Game Champions and a World Champion Competitive Eater, City of Gonzales firefighters/paramedics Eric and Daniel Guiffreda and the rest of this season's "The Amazing Race" competitors were introduced to TV audiences Wednesday night.

From Washington Square Park in New York, the 11 teams headed to the airport for a flight to Reykjavik, Iceland, where the real race began.

First challenge: traverse a massive canyon 150 feet above the Geitargljufur River in order to retrieve an Icelandic flag to trade for the next clue in the race. Next up was riding dune buggies in a hunt for letters that spelled a clue to their next destination. Making it to the town square, the teams had to ask locals some questions about Iceland in order to get their next clue.

Eventually, the 33-year-old Guiffreda twins became the eighth team to reach the finish line, securing spots on next week's leg of the race.

"They sure made us nervous," the Guiffredas' mom, Donna Reno, posted on Facebook right after the show. 

Meanwhile, her sons were finally able to share photos from October taken at Louis Armstrong airport before they headed to New York to begin filming for the series.

"Headed to the race!" Eric Guiffreda posted along with the pictures.

Finishing last and thus eliminated from the competition last night were Pennsylvania models Dessie Mitcheson and Kayla Fitzgerald.

The winning team for the CBS show's 30th season gets $1 million.

"The Amazing Race" airs at 7 p.m. Wednesdays.
