Bush: A Running Conversation by Bob Wischnia & Paul Carrozza" at http://www.runnersworld.com/footnotes/gwbush/20questions.html which has the following Q and A with Bush:
Q "I know you ran a marathon in Houston in 1993. What are your recollections from that?
A"I  was distraught after my dad was defeated in 1992 so I decided I was going to set a little project for myself. I wanted to run the White Rock Marathon in Dallas so I began training intensely for it. I gave myself a month to train for it and pushed myself incredibly hard as this after-election therapy. But I got sick and it was really a foolish attempt on my part.
Q"It takes a lot longer than a month to get ready for a marathon."
A"Dr. Ken Cooper of the Cooper Clinic told me the same thing. So I set my sights on Houston which gave me some more time to train. I ran it in 3:44. I ran the first mile in 8 _ minutes and the last mile in 8 _ minutes. It was one of the great experiences of my life."
