WARREN MACDONALD’s life’s boundaries were redefined in April 1997 with his accident on North Queensland’s (Australia) Hinchinbrook Island. Climbing to the Island’s tallest peak, he became trapped beneath a one-ton slab boulder in a freak rock fall. Two days later he was rescued, only to undergo the amputation of both legs at mid thigh. Just ten months later, he climbed Tasmania’s Cradle Mountain using a modified wheelchair and the seat of his pants. In February 2003, he became the first double above-knee amputee to reach the summit of Africa’s tallest peak, Mt Kilimanjaro (19,222ft), and more recently, in a spectacular effort requiring more than 2,800 pull-ups over 4 days, created history once again in an ascent of America’s tallest cliff face, El Capitan.
