"It's something that I've trained for 14 years," he said.

Later this month, Zwick will scale 2,000 feet of Kolob Canyon in Utah's Zion National Park alone.

"I will climb up to various points along the wall, I will then repel back down, retrieve gear that I used to climb that section of rock," he said. "I will then haul my gear up to the point where I'm at and then climb the next section and then come back down and repeat that for about 2,000 feet."

Because of the way he's doing it, the 2,000 feet will likely turn into 6,000.

Zwick will spend several days living on the mountain, including sleeping on the ledge he will be mounting every night.

"The ledge is actually relatively comfortable because I can sprawl out on it and I don't have to worry about being cramped on a small sloping rock ledge that I might slip off of in the middle of the night," he said.

Zwick is doing this for to raise awareness for the Rocky Mountain MS Center.

"It's an amazing resource with amazing people that work there that are really striving on a daily basis to provide resources education seminars to people that really need help," Zwick said.

Zwick has raised several thousand dollars for the Rocky Mountain MS Center.

No one in his family has MS. A friend's mom was diagnosed when he was a teenager.
