Course Map

As a part of our COVID-19 mitigation plan for the 2021 edition of the Grasslands Trail Run, the 50 Mile Race will run the 4.8 mile out-and-back segment at the end of the race instead of at the beginning. Because this section is mostly single track it has historically been congested at the start of the race with little opportunity for runners to spread out. The final segment will be 4.8 mies vs 5.3 miles in prior years.

The Grasslands Trail Run course uses the multi-use trail system at the LBJ National Grasslands. The trails used for the course are the Blue, White, Yellow, and Red trails. Note: the colors in the tables to the right correspond to the colors of the trails in the course map to the left.
