Rock and Roll Marathon...t-minus 6 days

My first 1/2 marathon is set to go this Sunday in downtown STL.  I have been training for 11 weeks and since that time, I have participated in 2 5k runs.  I will be walking/jogging this 1/2 marathon but my goal is to run a full 1/2.   Thinking maybe the Disney Marathon in January 2013.  I think I would look wearing a tiara!
