IT WAS only right that sisters Lucy and Emilia Pelosi entered Channel 7's reality series The Amazing Race Australia together.
The bubbly pair, who both work as teachers and live together at Kogarah Bay, are used to each other's company and knew they wouldn't mind chasing the $250,000 prize around the world.
Lucy 36, and Emilia, 31, think Australia will see them as the "underdogs" when the second season airs next week.
"We didn't take things too seriously and just had fun with it," Emilia said of their time on the show filmed late last year.
"We struggled with some of the physical challenges so most teams didn't see us as a threat. But we really were trying hard."
The show sees 11 teams of two compete in challenges around the world until one duo takes the $250,000 grand prize.
Teams this season travelled more than 65,000 kilometres across four continents, performing a range of challenges testing their stamina and personal relationships.
The sisters were chosen for the first season but pulled out the day before they were due to leave when their mum was diagnosed with cancer.
Emilia said their mum, who went through chemotherapy, was their motivation to enter the second season.
"She knows this has been our dream forever. I think it's made us more determined," Emilia said.
The pair both speak Italian, thanks to their heritage, and French, which they said helped them along the way.
While Emilia hadn't previously been to any of the countries they visited during filming, the both thought they would head back to some of the places.
"The good thing about the race was that we could experience different places that we wouldn't normally choose," Lucy said.
The Amazing Race Australia airs on Channel 7 at 9pm Wednesday, May 30.
