It's the most breathtaking stunt you'll ever see. A woman daredevil does a split on a thin wire 1,000 feet in the air. Then, she does a jaw-dropping move and hangs by her ankles.
Ashburn told INSIDE EDITION, "When you overcome a challenge like that it feels amazing, and you just want to do more, longer, bigger, higher."
Ashburn and Sukiennick wear a safety harness in case they fall.
"It's actually not that dangerous because as long as I have my harness on and my leash, even if I fall totally out-of-control on the highline, I'm only going to fall about six or seven feet below the line and I'm just going to dangle there," said Ashburn.
Their friend Jill slipped the first time she tried highlining, but was held up by the harness.
So do we really need to say this—people, don't try this at home!
Ashburn said, "Highlining is dangerous, but we do what we do because it's fun."
