Warren Macdonald's boundaries were redefined in 1997 while climbing Hinchinbrook Island's tallest peak, when he became trapped beneath a one-ton slab boulder in a freak rock fall accident.
Two days later he was rescued, only to undergo the amputation of both legs at mid-thigh. Ten months later he climbed Tasmania's Cradle Mountain using a modified wheelchair and the seat of his pants. In 2003, Warren became the first double above-knee amputee to reach the summit of Mount Kilimanjaro, Africa's tallest peak.
He is also the only above-knee amputee to make an ascent of the Weeping Wall, Canada's landmark frozen waterfall, and more recently, in a spectacular effort requiring more than 2800 pull-ups over four days, he made history once again in an ascent of El Capitan, America's tallest cliff face.
He is the author of best-seller "A Test of Will", featured on a series on the Discovery Channel. His film "The Second Step", documenting the epic four-week journey to Federation Peak, has been acclaimed worldwide, screening on National Geographic and winning eight international awards.
Warren Macdonald has been featured on numerous news and current affairs programs, including Larry King Live and The Oprah Winfrey Show. He has written articles for CNN's World Edition, Australian Geographic, Speaking of Impact and Professional Speaker magazine, among others.
