It’s a good thing Nik Wallenda and his sister Lijana Wallenda don’t hold any childhood grudges. Otherwise, their dual tightrope walk at Charlotte Motor Speedway could have made for a difficult situation. The Wallendas of the famous Flying Wallendas family performed at the Bank of America 500 during the pre-race show on Saturday.

The 460-foot tightrope wire was suspended 150 feet over the race track, which doesn’t sound too terrifying considering some of Nik’s previous walks, such as the one at Niagara Falls. Each sibling started out at opposite ends of the rope and had to make it to the other side. The walk didn’t get too difficult until Nik and Lijana had to get past each other at the halfway point. Watch Nik very carefully step over his sister at 150 feet in the air:

Before the tightrope walk, NASCAR driver Clint Bowyer gave Nik a warning about the cables at Charlotte Motor Speedway, referring to a freak accident that occurred at CMS earlier this year when a TV cable snapped and injured several fans.

Hey Nick Wallenda! This track doesn't exactly have a good track record with cables…

Nik and Lijana Wallenda completed the tightrope walk successfully, of course, and the siblings were happy to do the stunt together. “It was exciting to perform together again,” said Nik Wallenda. “We don’t perform like this very often. We’ve never performed this high and this far apart before and this was the first time in many, many years.”
