The Grasslands Trail Run has been a North Texas Trail Running tradition since 1999. The race is held annually on the third weekend in March at the LBJ National Grasslands near Decatur, TX on more than 20,000 acres managed by the U.S. Forest Service. The trails loop among rolling hills and through a mixture of pine and oak grove forests, and open grassland fields. Unique to North Texas trail races, there is approximately 45 miles of non-overlapping trail. The Marathon, Half Marathon and 15K are all held on 100% unique trail. With a gentle elevation profile (approximately 4000 ft of elevation gain in the 100 miler) the race course is very runnable which makes it an excellent choice as a first trail race in any of the distances offered. Run a race on one or both days and enjoy the beauty of one of our National Grasslands while sharing the trails with horses and running past cows—don’t let the cows out!
