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 50-mile runners will start with a correction loop, followed by the blue, white, yellow and red trails. The course map shows all loops with aid stations marked.

Race Swag and Awards

All participants will receive a short-sleeved race shirt. People love our shirts--they are soft, tri-blend shirts that are super comfortable.

All finishers will earn a finisher’s medal, unique to their race distance.

The top 3 male and female finishers, and the top male and female Master’s finishers (40+), in all three distances will earn prizes. Each year, we try to find something that you'll really use. Past awards have included gear bags, seat towels, insulated engraved cups, coolers, etc.

One of the best parts of the Grasslands Trail Run is the race community. We serve all participants a fully catered post-race meal. You won't want to miss the fun! Tickets for family and friends can also be purchased when you register if you have guests attending the race.
