The Dallas Marathon is the largest marathon in Texas and one of the longest-running marathons in the United States. The course starts in downtown Dallas at approximately 131 m elevation and finishes in downtown Dallas at around 137 m, following a loop route that showcases many of the city’s neighborhoods and landmarks. Runners pass through areas such as Uptown, Highland Park, and White Rock Lake, where scenic views of the lake provide one of the highlights of the race. The course features several rolling hills, particularly in the early miles and again around the White Rock Lake section, making it moderately challenging compared with flatter city marathons. Known for its energetic crowds and well-organized event, the Dallas Marathon attracts runners from across the United States.

Before you go

Pro tips

Racing it

01
Ease into the early hills
The rolling hills come early, so run the first climbs through Uptown by effort rather than pace. Banking time there will cost you later on this loop.
From the elevation profile
02
Save something for White Rock
A second set of rolling hills hits around White Rock Lake, where the lake views are the race highlight. Keep reserves so you can still run this section strongly.
From the elevation profile
03
Count the whole 257 meters
Total climbing of 257 m across a loop that starts near 131 m and finishes near 137 m means constant small ups and downs. Effort, not splits, is your best guide.

04
Cool-weather racing
Typical race-day temperature is 11.2 C, cool enough to race hard but chilly at the start. Wear layers you can shed and expect to warm up within a few miles.

05
Loop start and finish
The route is a loop from downtown back to downtown, so you finish near where you began and can leave a bag or a friend at the start area. The half marathon runs the same day.
From the layout

In Dallas, TX

Ride the rail
DART light rail and buses reach downtown and the start area, and they are the easiest way around on race morning when streets along the course are closed to cars.
Where to watch
Spectators can catch runners downtown near the start and finish, in Uptown, and at White Rock Lake, where the paths and parkland leave plenty of room.
Dallas afterwards
The city is spread out, so plan recovery around a district rather than a walk: the Katy Trail and White Rock Lake for easy miles, Deep Ellum or Bishop Arts for food and music.
