About Mary Walker

Mary Walker is an American former professional rodeo cowgirl who specialized in barrel racing. She won the Women's Professional Rodeo Association barrel racing world championship in 2012. Despite several traumatic events in the two preceding years, she persevered. She also became the oldest woman, at 53, in rodeo to win a world championship in the barrel racing event at the National Finals Rodeo. She was later surpassed by Mary Burger in 2016 when Burger won at age 68. She lost her only child to a car accident in 2011. Two months later, Latte, her horse, fell on her during competition and severely injured her. It was about a year and a half after these incidents that she won her world title. Walker was inducted into the National Cowgirl Museum and Hall of Fame in 2013.
