Rehoboth Beach Seashore Marathon

Prepare for a festive coastal run at the Rehoboth Beach Seashore Marathon and Half Marathon on December 5, 2026, in scenic Rehoboth Beach, Delaware. This annual event is renowned for its charming atmosphere, well-organized course, and a legendary post-race celebration. Runners will find a generally flat and fast course, ideal for chasing personal bests or a Boston Marathon qualifying time, with only minor elevation changes primarily within Cape Henlopen State Park. Typical race day conditions in early December offer cool temperatures, with highs around 58°F and lows around 38°F, and a 14% chance of precipitation, creating comfortable running weather.

The out-and-back course treats participants to a diverse visual journey, beginning at the historic Rehoboth Avenue Bandstand. Runners will wind through vibrant town streets, along the iconic boardwalk with stunning ocean views, and into the tranquil landscapes of Cape Henlopen State Park, featuring forests, wetlands, and coastal habitats where the Atlantic meets the Delaware Bay. Both distances share the initial miles before the marathoners venture further into Lewes and the park, eventually returning to join the half marathon route on the Junction & Breakwater Trail. While mostly paved, sections of the course utilize a hard-packed gravel trail, offering a varied terrain experience. Volunteers are lauded for their enthusiastic support at aid stations, strategically placed approximately every two miles and stocked with water and Gatorade, along with gels at key points.

What truly sets the Rehoboth Beach Seashore Marathon apart is its vibrant energy and exceptional finish-line experience. As you approach the end, the inspiring "tunnel of flags" provides a motivational boost, showcasing flags from various countries and states. Crossing the finish line on 4th Street, runners are welcomed to one of the country's best post-race parties, boasting unlimited food options—from breakfast fare to burgers—three complimentary Dogfish Head beers, live music, and a lively atmosphere perfect for celebrating your accomplishment. This event is a favorite among "50-Staters" and those seeking a memorable race with small-town hospitality. Given its popularity and Boston Qualifier status, early registration and accommodation booking are highly recommended.
