Thank you for your interest in volunteering for this race! The Gar Williams half marathon would not be possible without the help of volunteers – your time and energy are greatly appreciated, and we need lots of volunteers for this race.

We will need Volunteers starting at 7:00 am, all the way through 12:30 pm on December 5th.

Once you register you will receive further instructions about your volunteer role.

Carderock Directions

Directions: Take the Capital Beltway (I-495), to the Clara Barton Parkway headed west, outside the Beltway.  Take the first exit, which is for both Carderock and the Naval Surface Warfare Center (Carderock Division). Turn left at the stop sign at the top of the ramp to cross the parkway. After passing under the canal, turn right and proceed to the third parking area at the end of the road. You may park at one of the other areas, wherever you can find an open space.
