Mary Burger is not your average grandmother. Burger was born in 1948, and began barrel racing in 1984. Barrel racing is a rodeo event during which participants ride horses around barrels in a cloverleaf pattern. The winner is the rider that can complete the course in the fastest time. Even though participants in the sport are typically younger men, Mary Burger has won world championships for barrel racing. In the first half of 2016, she earned more than $100,000 in prize money. Burger credits her horse, Mo, for her continued success in the sport. Burger has told the Global News, "You know, several years back I used to think, 'Well, I've got a little age on me.' But I've had so many people come up and say 'you're my inspiration.' When I hear the crowd go, I just get goosebumps all over, and I'm really, really proud."
