Delaware Running Festival

Now in its 17th edition, the Delaware Running Festival half marathon has built a loyal following: roughly 1,550 runners toed the line recently, with participants hailing from some 33 states and about 14% returning year after year. The USATF-certified course is famously flat — elevation gain is negligible — making it a prime target for Boston qualifiers; historically, 10–12% of marathoners earn their BQ here, and half marathoners benefit from the same forgiving profile.

The route showcases Wilmington’s character, winding through historic downtown, past Rodney Square, and into leafy Brandywine Park alongside the Brandywine River. The parkways and neighborhoods offer a tour of the city’s most interesting corners without confusing turns. Runners finish at Tubman-Garrett Riverfront Park, where a lively post-race party awaits with live music, vendors, and activities for the whole family.

With a growing field and consistent race-day weather averaging 45–65°F, the event combines a serious racing opportunity with a warm, community-driven atmosphere. Whether chasing a PR or exploring Delaware’s first city, this half marathon delivers a well-rounded experience.
