“She has the spirit to run,” Leadville local Marvin Sandoval said of his miniature burro Buttercup after winning the Boom Days Pack Burro Race.
At just 33 inches tall, Buttercup is the first miniature burro to have won both Fairplay’s World Championship Pack Burro Race and Leadville’s Boom Days race. The duo will compete for the Triple Crown of Pack Burro Racing next weekend in Buena Vista.
When Sandoval was growing up in Leadville, he never imagined that he would one day race burros. Instead, Sandoval spent much of his 30s focusing on a variety of ultra endurance races and the annual Leadman competition.
