Trail Information

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.

Aid Stations

This is a cupless race. Please bring your own hydration device to carry and consume fluids on the course. Water and endurance drink will be available at all aid stations along with favorite food items such as bananas, oranges, peanut butter and jelly sandwiches, potato chips, Oreos, fig cookies, soda, Salt Stick and much more.

Drop Bags

Supplies for 50-Mile and Marathon participants can be left in drop bags at the Start/Finish aid station. Remember to pick up your drop bag at the end of the race.

Registration and Refund Policy

We understand that sometimes your plans change. Refunds are allowed if requested before February 1. We will refund 75% of your registration price, not including the transaction fee.

We allow changes in race distance as long as we still have openings in that distance. If you are moving to a longer distance, you will need to pay the difference. If you are moving to a shorter distance, you will not get that difference back.

We allow bib transfers until March 8.* If you are interested in transferring your bib to a friend, please contact us immediately. It is very important for the safety of all runners that we have contact and medical information. If the shirt order has already been placed, your friend will need to accept the shirt size that you ordered. A $10 administration fee (plus transaction fee) will be charged to the person who is accepting the bib transfer.

*We will not allow transfers if the race is sold out and people are on a wait list. In that case, we will follow our refund policy and allow the next person on the wait list to register.

Thank you

The Grasslands Trail Run was founded in 1999 by Suzi Cope, the first female to complete the Grand Slam of Ultrarunning. It has continued year after year because of the support of both runners and volunteers. Chris Barnwell began directing the race in 2015 as a volunteer race director through the North Texas Trail Runners. In 2016, Chris acquired both Grasslands and the Rockledge Rumble Trail Run with the goal to continue these Texas traditions for many years to come.

Thank you to all runners and volunteers for your continued support to this event.
