Race Description

The Grasslands Trail Run is held in the Lyndon B. Johnson National Grasslands, more than 20,000 acres managed by the U.S. Forest Service and situated north of Fort Worth. The trails loop among rolling hills and through a mixture of pine and oak grove forests, open fields, and livestock.

The race uses a series of trails that start and finish at TADRA Point Trailhead. The half marathon uses the blue trail; the marathon uses the white and blue trails; and 100-mile and 50-mile runners use the blue, white, yellow and red trails. The 15K (Sunday) will use the yellow trail. The course map shows all loops with aid stations marked.

Full race Information can be found on our website:

2024 will be the first year of the 100-mile race, and we are still updating our website. A few important details:

The 100-mile race will use the same trails and order as the 50-mile, twice. However, we will provide an additional loop to get the runners to 100 miles. We are finalizing these details.

This is a flat, non-technical course with a 30-hour cut-off for the 100 mile distance. We believe this is the perfect 100 mile to complete in under 30 hours, or get a new PR.

Runners in the 50-mile, Marathon and Half Marathon will have generous cutoffs. Runners in the 15K will have a 3.5 hour cutoff, the same time the 100 mile distance finishes on Sunday.
