The Experience

The Coastal Delaware Running Festival, now in its 11th edition, draws around 1,250 finishers from 40 states each April to Dewey Beach. Runners launch from the Rehoboth Beach Boardwalk and wind through Delaware State Park paths and historic Lewes. The course is flat and fast—a PR magnet—and stays cool with typical race-day temps in the 45–58°F range.

The festival includes a full marathon (a Boston Qualifier), half marathon, 9K, and 5K, all sharing the same rapid, scenic route. About 19% of runners return year after year, a loyal core that speaks to the race's welcoming vibe. The finish line celebration overflows with complimentary beer, food, and live music, making the post-race party as much a draw as the race itself.

Proceeds benefit the Delaware Seashore Preservation Foundation and local charities, adding purpose to the pavement. Whether hunting a personal best or a scenic coastal tour, this growing event delivers a polished, community-minded weekend by the sea.
