Twins Anna and Kristy Berington were born five minutes apart. Yesterday, again just minutes apart, they started off on the 975-mile Iditarod Trail, the first twins ever to compete in the race.

Kristy is a two-time Iditarod finisher; Anna is competing in her first Iditarod.

“Our mom didn’t even know she was having twins until Anna was born,” Kristy, who is five minutes older than her sister, told the Anchorage Daily News. “She never even got an ultrasound and our heartbeats were completely identical.”

While sled dog racing tends to run in families, Iditarod officials say the twins are the first — and the first sisters — to compete in an Iditarod.

The twins are also known to turn a few heads in a sport where — at least in the Iditarod — three of four racers are men.

“A lot of people kind of get the feeling that she’s just a pretty face — that she doesn’t know what she’s doing, that kind of thing,” Anna said of Kristy. “But she’s definitely proven that she is a dog musher.”

Kristy finished 39th in the 2010 and 29th in 2011. She came in ninth in this year’s Yukon Quest, a 1,000-mile race — and won the Veterinarian’s Choice Award for best dog care among the mushers.

The sisters grew up in northern Wisconsin, where they built dog sleds from downhill skis and a milk crate and used their Great Pyrenees and a border collie as their sled dogs, the Daily News reports.

The Beringtons began the race within minutes of each other at the timed start Sunday in Willow. Kristy drew position No. 31; Anna is No. 33.
