Thank you for supporting American Heart Association!  I am running the Chicago Marathon to support a great cause and in fond memory of my father, Peter Mueller, who passed away from heart disease in 2014.  If all goes to plan, this will be marathon #15.  I'm older and slower than my first one 30 years ago, but I appreciate the opportunity so much more keenly now and will feel lucky standing on the starting line.  Your contribution is greatly appreciated.
