MONTREAL- It's not all that hard to find Marie-Eve and Frederique Cigna. They're in a pool six days a week.

The sisters, born only 16 months apart, grew up pushing each other to succeed.

And the hard work has paid off: both girls won medals at this years national championships.

"I love the feeling of the water," said Marie-Eve, 15. "I love that I have to push myself to the limit in every race that I do."

They used to race each other as rivals, but now they dominate their respected events.

Frederique, 14, is a two-time national butterfly gold medalist. In 2010, she broke a 30-year-old national record.

"When I lose I don't like that feeling," she said. "So I try my best to never lose."

Marie-Eve is better at longer distances. She's a two-time national silver medalist in the 5 kilometer race.

Her strategy is simple: lead the race from beginning to end.

"I just feel better when I'm in front of other people and that's what it like," she said. "I guess I like to be the best."

The fact their in it together keeps them motivated. Their coach at the Camo Swimming Club says they're always putting in extra work.

"They want to have more," Jean-Pierre Laforest. "I don't know if they need more but they do more and it shows at important times."

Their father is happy both girls share a passion.

"Honestly I'm proud of seeing them have a goal in life and sharing the same goal," said Alexandre Cigna.

The sisters have big plans – to win at the Olympics.
