Quote comes from a column Dunbar wrote on Father's Day for his dad about how much fun he had when his dad let him attend the 2004 Trials with him and his friends as a 7th grader.

We got a chance to meet a lot of great people like Alberto Salazar, who I’ll never forget told me, “There’s no such thing as too many miles, kid.” I thought he was joking but now I’m not sure.
My favorite father's day related quote from the piece is as follows:

I’m so thankful to get that Olympic Trials experience at a young age. I’m more thankful my Dad never forced me into running and my love developed on it’s own. I am grateful everyday I get to share my journey in the sport with him.
My dad taught me to enjoy the process, be a student of the sport, have patience, and seize every opportunity with a full heart.
