Two brothers from San Francisco claimed they have broken the record for the longest Highline ever walked in the city. 

Earlier this month, brothers Moises and Daniel Monterrubio said they crossed a 2,800-foot Highline across Taft Point west in the Yosemite National Park. The point has a series of gulleys plunging 1,600 feet. 

The brothers then told the San Francisco Chronicle that they have set a record for the longest highline ever walked in both the park and California, as reported by the San Francisco Gate

The group spent six days to navigate across the park through the webbing. The group said they received permission from staffers. 

What is a highline?

Highlining is a high-altitude slacklining, in which a narrow strip of nylon webbing is strung between two anchor points. The webbing then serves as a balance beam. People who highline walk on the webbing by carefully heel-toeing from one anchor point to the other. 

Highliners wear a waist-harness linked to a steel ring around the webbing. This ensures that they remain attached to the webbing and can haul themselves back up in case of a fall.
