In 2013, Mirinda ran a 2:50:38 marathon at the Ironman World Championship—only two men ran faster. 3x World Champ “Rinny" is now taking a year off to “grow a little human.” Sara and Alyssa find out how she adapted her training schedule—and life—what she is up to at week 23, and what she expects for the future. We also learn her secret to running fast off the bike. Kristin Beckstrom Radcliffe calls in to ask Rinny a mom-specific question. (Originally produced for WiSP Sports)
