Natalie Grabow, an 80-year-old grandmother, has become the oldest woman to finish the Ironman World Championship in Kailua-Kona, Hawaii.
Just 20 years ago, Grabow was learning to swim. At age 59, she decided to change that, so she could face an even bigger challenge.
"It was a big hurdle I had to overcome," Grabow told NPR via email, "in order to do a triathlon."
Grabow competed in the triathlon, which included a swim in the ocean water of Kailua Bay, and finished the race to loud cheers and a crowd chanting her first name.
