The RBC Brooklyn Half takes you on a 13.1-mile tour through the Borough of Kings, from Prospect Park to the Coney Island Boardwalk. NYRR is thrilled to welcome Royal Bank of Canada (RBC) as the title sponsor of the new RBC Brooklyn Half. The race starts at Prospect Park and ends with a finish like no other on the Coney Island boardwalk. This half marathon takes runners on a brand-new course through Grand Army Plaza, around Prospect Park, down Ocean Parkway, and along the Coney Island boardwalk to the finish.
