Watch: 500-Meter Slackline Walk Between Desert Towers

This accomplishment boggles the mind. On November 15, 2015, Théo Sanson walked nearly 500 meters on a highline rigged from The Rectory to Castleton Tower in Castle Valley, Utah. The walk likely set a new world record.


If you have tried slacklining, you already know it’s not easy. As the line gets longer, more difficulty arises. In this walk, Sanson had to overcome both the instability of the line from side to side and sag in the line due to its tremendous length.

The film by Camp4 Collective gloriously captures the highline walk. As stated in the video’s notes, rigging the line was perhaps as significant a feat as walking it. The team to make this happen included Andy Lewis, Brent Cain, Aleta Edinger, Sylvan Slacks, Scott Rogers, Brian Mosbaugh, Homer Manson, Ryan Zorg, Thibault Arrappiccatu, Mathieu Pertus, Crack Mouse, Sara Zorg, Guillaume Rolland, Antony Newton and Mimi Guesdon

It was filmed and edited by Tim Kemple, Renan Ozturk and Anson Fogel.
