Australia’s Mirinda “Rinny” Carfrae revealed today that she and husband Timothy O’Donnell, also a professional triathlete, are expecting a baby—due on Aug. 10 of this year.

The three-time Ironman world champion has proven to be one of the top Ironman athletes to ever compete, finishing on the Kona podium in seven of her eight attempts at the race. She will sit out this year’s event for the first time since she first competed in 2009.

Carfrae used her social media channels to reveal the news, saying “Setting up for a different kind of transition, @tointri & I are thrilled to announce baby O’Donnell! Due August 10th 2017.”
