33 - Mirinda Carfrae from 5'3" Basketball Pipsqueak to 3-time Ironman World Champion

Meet Mirinda "Rinny" Carfrae. One of the best Ironman athletes of all time. She won the Hawaii Ironman in 2010, 2013 and 2014. She's been on the podium seven times. She toed the starting line eight times. The only time she didn't finish in the top three was when she was hit by a car during a training ride just days before the race in 2015. But she wasn't always an Ironman rockstar.
