Omaha mom completes Ironman competitions on every continent

"I don't feel 57!" And she certainly doesn't move like it. "I've never been in better shape than when I'm training for these races," Lisa Smith Cimino explained. Last year, the Omaha mom competed in two Ironman competitions. Each consists of a 2.4-mile swim, 112-mile bike and 26.2-mile run. What's extra special is that having completed 10 Ironmans total — Lisa has done at least one on every continent. "There isn't one in Antarctica. So ... thank goodness," she laughed. Now, 20 years into her journey as an endurance athlete, Lisa is setting an example for her four children.
