About the race
The Grasslands Trail Run is an annual trail running event held on the third weekend of March at the Lyndon B. Johnson National Grasslands near Decatur, TX. The grasslands cover more than 20,000 acres managed by the U.S. Forest Service and lie north of Fort Worth.

The event offers multiple distance options across the same general area:
- 100 Mile
- 50 Mile
- Marathon
- Half Marathon Saturday start
- 15K Sunday start
