People of all ages can participate in the zoo's annual 5K Run/Walk or 10K Run. Whether you're dressing up as a zoo animal and entering the costume contest, taking it easy with the 5k walk, or a serious runner wanting to end your great run with a refreshing brew, the Zoo Run run is for you. The 5K and 10K runs will be timed. Kids participating in the Roo Run Run can choose between a quarter mile, half mile, or a full mile run.
