How about running on Thanksgiving morning in anticipation of the high calorie feast. Put your turkey in the oven Thursday morning and let it simmer as you are pounding the pavement in the Galleria area with 12,000 other hungry runners.
Two races start at different times, 5k or 10k. You have the option of getting a timing chip or not, but really does it matter when you are hustling with your wings pushing against hundreds of other birds along the open road.
