Educator Peter Rettler has run every single day for over 30 years. Today on WTMJ Conversations, he tells WTMJ's Libby Collins how his journey began, continuing through hurdles like kidney stones, cancelled flights, and childbirth, and why he decided to turn his passion into a way to raise funds for the Wisconsin 9/11 Memorial in Kewaskum. It's all ahead on this invigorating edition of WTMJ Conversations!
