Grasslands Trail Run
The Grasslands Trail Run is a North Texas trail running event held annually since 1999 on the third weekend of March at the Lyndon B. Johnson National Grasslands near Decatur, Texas. The Grasslands area covers more than 20,000 acres managed by the U.S. Forest Service and lies north of Fort Worth.
Courses loop among rolling hills and pass through a mix of pine and oak grove forests, open fields, and areas used for livestock. Runners share the trails with horses and pass grazing cattle. Multiple race distances are offered over the event weekend.

- 50 Mile
- Marathon
- Half Marathon (Saturday start)
- 15K (Sunday start)
The event provides marked trail routes and aid stations as described in its race details. Results and historical finishing lists are maintained for past editions. The format separates some distances by day, with the half marathon on Saturday and the 15K on Sunday. Visit the organization's website for the most recent information.
