DALLAS - MetroPCS Dallas Marathon runners only get six-and-a-half hours to finish the 26.2-mile run through the city.
Runners on the full course will start in downtown Dallas, with the path taking them through the West Dallas Loop and over the Margaret Hunt Hill Bridge. Runners then sprint through the Dallas Design District, onto Turtle Creek and through Highland Park and the White Rock Lake area. The runners then head back through the Lakewood and Swiss Avenue Historic District and finish in downtown Dallas.
The corrals open early at 6 a.m. and close at 7:40 a.m.
Streets in the area of the race were already shut down Saturday night in preparation for the Sunday race, which starts at 8:05 a.m. at Main and South Market streets.
South Griffin Street between Memorial Drive and Young Street and Main Street between Houston and Ervay streets are among those closed off to traffic. That stretch will re-open when the finish line officially closes at 3 p.m.
From the start, runners will head west this year and can expect morning closures at West Commerce Street, Sylvan Avenue and Singleton Boulevard.
Access to Turtle Creek will be restricted and Mockingbird Lane between Hillside Drive and Buckner Boulevard whittles down to one lane in each direction.
Those in Highland Park, Lakewood and the White Rock Lake area can expect to see runners and some neighborhood street closures.
Heading to the finish line, Canton Street is also closed as runners head towards Dallas City Hall and the Dallas Convention Center for the end.
