If your kids aren’t up for a full-on 5K run, don’t worry. The New York Aquarium is organizing a tot-friendly course for families and casual runners on Coney Island's boardwalk. While a 5K is available for the more serious joggers, families can participate in a Family Fun Run to help raise money to protect endangered walruses. The 5K will begin at 8am and the Family Fun Run will start at 8:45am. All ages.
