Sister Madonna Bruder after winning the women’s 75-plus age division at Ironman Canada.

They say 70 is the new 50, but Sister Madonna Bruder is taking that age calculation to a whole new level. Called the “Iron Nun,” the 78-year-old Sister for Christian Community divides her time between ministry and triathlons.

Bruder, of Spokane, Washington, has completed over 325 triathlons, including 35 “Ironman”-class events consisting of a 2.4-mile swim, a 112-mile bike ride, and a 26-mile run. At the Hawaii Ironman over 10 years ago she became the oldest woman ever to complete the race, finishing in 16:59:03, an hour under the 17-hour midnight cutoff time. Her accomplishments have been featured on ABC News, complete with video, and in numerous internet stories.

"Well, you know, as long as God is giving you your health,” Bruder said, “there's no reason to stop.”
