His wife, Sarah, is expecting a baby in October 2012. He has found marriage and fatherhood suits him, and helps takes his mind of athletics. "I'm married now, and I can just see everything coming together. In 2009, I definitely thought [about athletics] too much and it really started affecting me. It affected my training because I didn't think I was training hard enough. I didn't think my training was going the way I wanted it to. Even though I was making my workouts, I was grasping for reasons why I wasn't running fast instead of forgetting about it and moving on." (nbcolympics.com, 19 Jun 2012)
