This is my determination of the probable route of the 1914 Electric Sociability Run adapted for current roads. This route was deduced from piecing together the route descriptions given in several contemporaneous newspaper accounts. The road around the Tidal Basin and Potomac Park was known as the “Speedway” in 1914. The route was 14 miles long and the Sociability Run began at the main entrance to the Smithsonian at 11:15 AM on Wednesday, May 27, 1914.

This photo of the Electric Sociability Run cars crossing a ford is probably at the crossing of Rock Creek at Klingle Ford about 400 yards north of the present day bridge at National Zoo Drive.
This photo of the Electric Vehicles parked along the road was likely taken at the finish at Joaquin Miller Cabin on Beach Drive in Rock Creek Park.
