Part of the mission of the Tarrant Regional Water district is to "Enhance the quality of life in North Texas communities by creating recreation opportunities around TRWD infrastructure to enable active lifestyles.' This means that they actively encourage and promote access to leisure running, biking, boating, etc., as well as to running races and triathlons. The first races held in DFW in the COVID era were held on TRWD land on the Trinity River in Fort Worth, and as of this writing, they have yet to cancel any (once they've been approved with proper safety protocols, etc.) For more information about TRWD, please click the icon in the Sponsors & Partners section of the page.

Marathon/ Half / Ultra Course Map / Elevation

The course roughly follows the shores of Marine Creek Lake, except for a 1/2-mile out and back at the northern tip that is done each lap. Most of it is through thick woods (windbreak) but the open areas may be windy. The surface is primarily concrete, and about 10' wide. The dam is crushed gravel.
There is no significant elevation on most of the course: on fresh legs, you might even think it's mostly flat (but if you do the double or the triple, you'll know better, lol!), The Dam is significantly higher than the rest of the course. Depending upon the day, the Dam will either be at the beginning or end of each loop. The finish is at the level of the Dam.
The course is run Clockwise Friday and Sunday, and Counter-clockwise on Saturday
Half Marathon: 2 laps
Full Marathon: 4 laps
Ultra Marathon: ~1-mile out-n-back along the dam, then 5 laps in the direction of the day.
