Jordon Milroy refuses to let cerebral palsy define him.
The 25-year-old AUT graduate heads to North America on November 2 in a bid to conquer the stairs of two of the continent's tallest towers: the CN Tower in Toronto and the Willis Tower in Chicago.
Milroy said the mammoth climbs - in which he will tackle an estimated 4000 steps in just two days - aimed to break down stereotypes around disabilities, as well as raise funds for charity.
"I climb to teach people that those with disabilities are capable too. I have a working brain and people shouldn't judge a book by its cover," Milroy said.
"In New Zealand people are used to seeing wheelchairs but are not at the stage of accepting the people in the wheelchairs. I want to change that."
