Both the full marathon and the half share the same starting line in downtown Dallas. From there, the course unfolds along a very gradual uphill for the first few miles, through the Baylor University Medical Center campus and the Old East Dallas neighborhood. After that, runners head northwest along Washington Avenue, Caddo Street and Lemmon Avenue, before turning right onto Turtle Creek Boulevard. After that, the next couple of miles keep runners alongside Turtle Creek, and once they pass the mile 5 marker the course begins another gradual uphill stretch that climbs about 160 feet over the next four miles. This section, through Dallas’s ritzy Highland Park neighborhood, is where the peak elevation of the half marathon course occurs, on Longview Street between miles 7 and 8. Once they pass the mile 8 marker, it’s (almost) all downhill from there. Long Stretches along Greenville Avenue, Munger Boulevard, Columbia Avenue and Main Street are followed by the home stretch along Canton and Young Streets, back in to the finish line near Pioneer Plaza and the cattle drive.
