Completing two marathons on crutches while partially paralyzed is a testament to the resilience of the human spirit. Three years after a spinal cord injury that left her without full mobility of her lower body, Hannah Gavios completed her second New York City Marathon - crossing the finish line on crutches in just over 11 hours, 18 minutes faster than last year. The sun had gone down by the time she reached the end of the 26.2-mile course. But achieving that milestone yet another time was a powerful reminder of everything she had overcome. In 2016, Gavios took a vacation to Thailand from her job teaching English in Vietnam. On her way back to her hotel one night, she feared she had gotten lost and asked for directions. But the person who had been guiding her ended up leading her to a dark, wooded area and attacked her, Gavios told CNN. While running away from her attacker, she fell off a cliff, tumbling 150 feet. The fall left her with a spinal cord injury that has affected muscles in her lower body. But it hasn't stopped her from living her life to the fullest. I always knew I was a strong person," the 26-year-old Queens, New York, resident said. "But I didn't know I was that strong. I also didn't realize how much of a fighter I was." Then she learned about Amanda Sullivan, who had been completing marathons on crutches after an auto accident left her disabled. If someone with a similar condition could finish a marathon, Gavios thought to herself, then she could, too.
