Wallenda, who performed the stunt without a safety harness, said the walk over downtown Sarasota took him about 15 minutes, WOFL-TV, Orlando, reported Tuesday.
"It was an amazing walk," he said. "There was more wind than I expected for sure and the cable moved a lot more than I wanted to. I wanted to stop when I was in the middle but there was no way I was able to."
Wallenda said before the walk he was not worried about walking the high wire without a harness.
"There's always concerns. There's always stress that goes into what I do. The truth is, there is risk in what I'm doing. Of course there's always worrying. I always say that fear is a choice. Danger is real. And that's something I have to deal with on a daily basis," he said.
U.S. 41 was closed during Wallenda's stunt, but has since reopened.
