Ritzenhein retired from professional running in May 2020. In an interview with Flotrack, he reminisced memories of his 16 year career. He stated that "I guess I'm not necessarily 25 and retiring in my prime. I have things that I wish that I have done in my career, but I'm also very satisfied, too. I think right now it's something that I thought a lot about the last year. I've had a lot of nostalgic moments, looking back a lot more than looking forward. So, I don't know that I had a lot more goals that I was looking to accomplish."
