About this race
Experience a scenic race course that takes you throughout historic downtown Wilmington. “The course has a lot of variety, and gives visitors a tour of many of the most interesting and beautiful parts of the city,” said one past participant from Pennsylvania.
The race route travels across beautiful Brandywine Park on the Brandywine River, along prestigious parkways, through historic neighborhoods of Wilmington and past downtown’s Rodney Square but without some of the confusing turns and crossovers. Choose from a full marathon, half-marathon, 10k, or 5k. Bring a friend to take advantage of our referral rewards to earn cash and gear. Non-runners can join us at start/finish line at Tubman-Garrett Riverfront Park for a great party with live music, vendors and activities for the whole family.
We believe this is your best chance to run a certified 26.2 mile road marathon in Delaware! We are a USATF certified Boston Marathon Qualifier and historically 10%-12% of our marathon runners have qualified for the Boston Marathon.
