Frenchman Théo Sanson attempted to set a world record for the longest slackline walk at nearly 500 meters, and the breathtaking trip is set hundreds of feet in the air in iconic Castle Valley, Utah.

Sanson made the crossing from The Rectory to Castleton Tower November 15, and the Vimeo posting states that the attempt is “likely a new record” while noting that setting up for the event was “perhaps as significant a feat as walking on it.”

Sanson's slackline attempt was shot by the company Camp 4 Collective. Visit their respective websites for more information about each.
