Fredericksburg Blue and Gray Half Marathon

Fredericksburg Blue and Gray Half Marathon is a 13.1-mile road race held in Fredericksburg, United States, in December.

Start and finish sit at Old Mill Park beside the Rappahannock River. From there the route heads into the residential streets of the historic town, using mostly wide paved paths rather than busy roads. The terrain is largely flat. The one notable exception is a long climb around the fifth mile, which is balanced by a downhill stretch near the ninth mile.

The race is a long-running December tradition in the town and has been held for more than two decades. Competition covers overall placings, masters and age-group categories. Strollers and dogs are not permitted on the course, and the race starts early in the morning.
