Nik Wallenda Reveals Grand Canyon Walk Details

Sarasota's famous wirewalker Nik Wallenda will be walking across the Grand Canyon on Sunday, June 23, live on the Discovery Channel, without a harness.

The announcement was made Monday morning on the Today Show by Natalie Morales during an interview with Wallenda.

Wallenda told Morales and host Matt Lauer that the walk will be 1,500 feet above the Colorado River, and 1,500 feet across on property of the Navajo Nation.

"It's taller than the Empire State Building, and it's something I wanted to do my entire life as well," Wallenda said on Today.

Wallenda said the location was partly selected to accommodate the television broadcast, or else the walk could last three hours. 

Wallenda had long voiced his displeasure over being required to wear a harness by ABC for his and instead, this walk will be broadcast by Discovery.

To help train for this walk, Wallenda said he will go to a "hurricane re-enactment center" in Miami, in addition to using wind machines at his Sarasota training grounds.

"There's a lot of updrafts and downdrafts," Wallenda said about the Grand Canyon.
