The Seawitch Fall Classic Racing Festival, held each October in Lewes & Rehoboth Beach, Delaware, is a spirited two-day Halloween-themed running weekend that includes a certified half marathon (21.1 km) on Saturday, followed by a 5 km Classic and a whimsical 1-mile Fright Walk on Sunday. Runners who take on both events land the “Spooky Challenge” and enjoy perks like chip timing, festive costume-friendly races, and custom awards, with options to support local charities like Toys for Tots. This fast and flat half marathon winds through scenic Cape Henlopen State Park in Lewes, while the 5 K and Fright Walk take participants through Rehoboth’s Grove Park pine trails—making it a delightful and inclusive holiday tradition for all kinds of runners.
