Runners start the out-and-back course for the Alexandria Running Festival Half Marathon along Eisenhower Avenue near the U.S. Patent and Trademark Office building, between Elizabeth Lane and John Cayle Street. From there, the course takes runners along the creek that runs past Cameron Run Regional Park and Hensley Park, and then makes two loops around Ben Brenman Park, and then heads back to the starting area for the race finish.
