Runners start the point-to-point course for San Diego’s USA Half Marathon Invitational at the intersection of B Street and 7th Avenue, just blocks from Balboa Park. From there, the course follows a looping route through the park and then into the city’s Hillcrest and Mission Hills neighborhoods, later taking runners past the San Diego International Airport and out onto Harbor Island before bringing them across the finish line in front of Waterfront Park.
