Runners World has published an excellent Q&A Sarah Lorge Butler has done with Mike Smith. I highly recommend it. Mike talks at length about why he's leaving NAU and how his pro atheltes are doing after the Olympics and how he thought he did there.
On why he's leaving:
I went from being a college coach to being a college coach and pro coach, and I think Budapest in 2023, that was a moment of big reflection for me. I’ve got four athletes in the World Championships. It’s also the NAU preseason cross country week, which is a very formative week of our season.
And I’ve got a four-month-old baby and her mom at home, and I felt so over committed. I felt like I was letting down my professional athletes, my college athletes, and my family. And I think that was maybe the start of looking at like, “All right, I really want to zero in my focus.”
