Momma K and I jokingly mentioned doing costumes with Papa J for the 5K and 10K and when he didn't reject our suggestion, we started planning our costumes. For the 5K we are a little more flexible with what we can get away with in the way of bulkiness and/or props since it is the shortest distance we are running over the weekend.
After much consideration, we decided to represent one of our favorite classic Disney movies......Marry Poppins!
