If some women have legs for days, then Caroline Arthur has legs for a solid week and a half.

The Australian ex-model is challenging the record for the longest legs in the world, putting her 51.6 inches against current Guinness World Records holder Svetlana Pankratova, a 6’5” Russian who officially has 51.9-inch legs.

“When I realized that my legs might be the longest in the world, I was super excited,” said Arthur in a video from Barcroft TV. “I think being so close, it’s worth contacting [the Guinness Book of World Records] and finding out.”

The 39-year-old Arthur started modeling as a teenager. Her amazingly long legs take up a whopping 69% of her height.

Arthur measured her legs from her hip to the ground and she feels that she has a good chance to challenge the record:

 

“I believe that they are definitely the longest in Australia and, as far as I know, in America too,” Arthur said.

The blonde beauty stays active by working out in the gym and playing tennis—take a look at some of her Instagram posts:
