It is held each year on the Sunday of Washington's Birthday Weekend and is conducted by the DC Road Runners Club.
The race was originally held in Arlington, Virginia, but after a few years, it was moved to Beltsville, Maryland.
The Greenbelt course started and finished at the recreation center of the NASA Goddard Space Flight Center and consisted of three loops around the Beltsville Agricultural Research Farm.
When NASA permanently closed access between the rec center and Good Hope Road, the race start was moved to Duvall High School, and finally to the Greenbelt Youth Center.
