Grasslands Trail Run

Grasslands Trail Run

The Grasslands Trail Run takes place in the Lyndon B. Johnson National Grasslands near Alvord, Texas, on equestrian trails that loop among rolling hills, pine and oak groves, open fields, and livestock-managed areas. Trails are described as non-technical.

Distances:

• 100 Mile
• 50 Mile
• Marathon
• Half Marathon
• 15K

The event uses marked trail loops that start and finish at TADRA Point Trailhead. Specific trail combinations are assigned by distance: the half marathon uses the blue trail; the marathon uses the white and blue trails; the 50 mile and 100 mile use the blue, white, yellow and red trails; the 15K uses the yellow trail. A course map shows all loops with aid stations marked.

Elevation gain for the 100 mile distance is listed as 4,000 feet. The 100 mile field has a 30-hour cutoff. The 15K has a 3.5 hour cutoff; other distances have generous cutoffs according to the organizer.

Runners receive a soft race shirt; 100 mile registrants may receive a long sleeve shirt if registered before the organizer’s shirt order deadline. Finishers earn awards: 100 mile finishers receive sub-20, sub-24 or finisher buckles, and finishers of the 50 mile, marathon, half marathon and 15K receive distance-specific medals.

Volunteers earn race credits that can be applied to future events; volunteer credits may be transferred under the organizer’s policy. Registration opens April 1, 2026.
