There’s a good reason people call Sister Madonna Buder the “Iron Nun”. She competed in her first triathlon at age 52 and went on to complete over 340 of them since then, including 46 Ironman triathlons. At age 86, she is still participating in the grueling endurance events and doesn’t plan on stopping anytime soon.
Born in July 1930, in St. Louis, Missouri, Marie Dorthy Buder was never really into running as a child. She was an active girl and even recalls winning a national championship in equestrian events as a 16-year-old, but sport was always just a hobby. At 14, Buder had already decided to become a nun, under the influence of the Visitation Sisters at the all-girls Visitation Academy in St. Louis, Missouri, that her parents put her in after sixth grade. At 23-years-old, Marie Dorothy fulfilled her calling in life and became Sister Madonna. In 1970, she left her congregation to join 38 other nuns from different backgrounds to found new and non-traditional community of Religious Sisters, independent from the authority of the Roman Catholic Church. This move gave her the freedom to choose her own ministry and lifestyle and would later lead her to discover her second calling – running.
Sister Madonna Buder only started running for fun at age 48, at the suggestion of a priest, who told her it was good for her body and mind. Before running her first official race, she consulted with Father John about whether it was a good idea, since people weren’t used to seeing a nun competing in running events. She told him she wanted to run for a good cause – Multiple Sclerosis (MS) – but wasn’t sure how the world would react to a nun running a race. The priest told her “Sister, I wish some of my priests would do what you’re doing,” and gave her his blessing.
