Next time you hike a state park, don't do it like Taylor VanAllen, and keep your feet confined to a straight line an inch wide.

He'll walk a wire 450 feet above Eldorado Canyon on Saturday, and 500 feet across. Foot-by-foot.

It hasn't been done since 1948, when the canyon was crossed by an 82-year-old guy named Ivy Baldwin. He didn't have a net, or a safety attachment.

VanAllen, 25, will have a leash, but it's still impressive nonetheless.

He started doing this in his backyard, and has worked his way up since.

But we're still baffled by how he'll do this, and why?

"I even ask myself why am I out here sometimes, and it's because it's so out of the ordinary to put yourself in a space like that. For me, I like being in that space because you're forcing yourself to be in an uncomfortable position, but you have to strategize how you can reason with yourself and find peace in that chaos. And that's something I've come to really love," he told us.

Highlining over Caves! Even know you're far away it feels as if you're getting sucked in. #caves #slackline #highline #slacklife #colorado #denver #native #coloradonative #mountainlife #outdooradventures #slackind #getoutstayout #climbing #alpine #elevate #oakley #cliffs #canyon

Even pros like VanAllen get scared sometimes. He said he blacks out for a second when he falls, but now he's used to it. In fact, he's trained himself to catch the line more often than relying on the leash.

It'll take VanAllen, who's from Morrison Colorado, about an hour to cross the canyon. He's been slacklining for six years and has been kicked out of parks for it more times than he can count.

This time he was invited. The event will raise money to help the state park fix up their trails.

VanAllen said he isn't nervous about the walk. He just wants the event to be a success.

The event runs from 10 a.m. to 2 p.m. at the state park.

Oh, and we had to ask: What happens if you have to go to the bathroom up there?

Taylor said it never happens.

"Something about your body, when you put it in an environment like that, very rarely do you have to go to the bathroom," he said with a laugh. "Your body knows it's about to go do something so it better hold whatever's in there."
