Sunday, March 22, 2015 • Wilmington, DE • Course Map
Set for its 52nd annual running through the streets of Delaware’s largest city on the first full weekend after St. Patrick’s Day in March 2015, the Caesar Rodney Half Marathon & 5K takes runners on an out-and-back tour of the city, with much of the course unfolding along the banks of the Christina River and Brandywine Creek.
More than 1,400 runners and walkers crossed the finish line in both races combined in 2014, for an event that also serves as a fundraiser for the Delaware chapter of the American Lung Association, whose programs promote clean air, the prevention of lung disease and fight the environmental conditions and pollutants that cause lung disease in the Delaware, New Jersey, Pennsylvania and West Virginia areas.
The race is often described as “the granddaddy of Delaware road races” thanks to its long history here, and often draws runners from as many as 20 countries around the world each year — and at more than half a century old, it’s been called the oldest continuously running half marathon in the nation.
Runners start and finish the out-and-back course for the race in downtown Wilmington near Rodney Square, and from there head out for stretches along Brandywine Creek and the river, including stretches that run past the Russell Peterson Wildlife Refuge, Brandywine Park and Rockford Park.
The race finishes just a few blocks from where it started, at Rodney Square on the corner of 10th and Market Streets. Those running in the half marathon must be able to complete the race within 3 hours, while those running the 5K must be able to finish their race within one hour.
Because the 5K finishes before the half marathon starts, you can enter and run both races (if you’re feeling really ambitious). Organizers note also that unless there’s a state of emergency or other warning issued by the National Weather Service that indicates conditions are too hazardous to run the race, “we run in all weather.”
