Gar Williams Half Marathon

Sunday, December 4, 2022 • Carderock, MD • Course Map

Run in previous years near the Belle Haven Marina area, since 2010 the Gar Williams Half Marathon has been run along the Potomac River and the C&O Canal Path, along an out-and-back course that starts and finishes at the Carderock Recreation Area, which is part of the National Park Service along the George Washington Parkway.

Named for the past president of both the Road Runners Club of America and the DC Road Runners club, this race is described by participants as a hilly, challenging course — and is always run in some of the Washington area’s coldest weather.

All those interested in participating in this low-key event are asked to make the drive to Carderock Recreation Area (not the Carderock Recreation Park) in Carderock, Md., which lies just south of the famed Congressional Country Club.

The race usually draws between 150 to 200 runners out for what can be a very cold race — or can be sunny and mild, depending on the weather in the days leading up to the race.
