Volunteers will man intersections along the walk route and guide volunteers. They will present themselves to a coordinator who will provide them with a map detailing their assignment location and also a high-vis vest. The instructions on the map will also detail if they need to stay there for one or two laps of the 5K circuit. They will then proceed to the assigned point and wait there for the arrival of the walkers and ensure they observe traffic signals. Project is accessible by Smithsonian Metro, and travel time is included.
