Runners in the half marathon will start and finish their race at the Carderock Recreation Area, which lies just off the Clara Barton Parkway near Potomac. From there, the course takes runners out on an out-and-back route that takes them out to the mid-way turnaround point at about the 6.5-mile point of the race; after that, runners then make their way back to the finish line area along the route they’ve just covered.
Note: The course map above provides the approximate route for the race. Though every effort has been made to ensure its accuracy, changes are sometimes made to race routes due to weather conditions, road closures or other circumstances that can require a course to be changed.
