The LBJ National Grasslands features over 75 miles of trails. All trails start and end at the TADRA Point Trailhead. The Grasslands Trail Run course uses approximately 45 miles of the trail system. The race uses the BLUE, WHITE, YELLOW, and RED trails. The trails are well marked with many different kinds of permanent markings. These include painted blazes on trees, painted horseshoes nailed to trees, wooden posts and more recently the forest service has been installing steel mile markers. Some the painted blazes can be faded, so please make sure you look closely. This is especially important on some sections of the White and Yellow trails where the faded colors can blend into the posts.
Notice that some of images show multiple colored blazes. These are sections of trail are where multiple trails converge. An example of this is in the first image below. In this image there are five blazes. This is where all five trails converge coming into (or leaving) TADRA Point. Notice there is also an ORANGE blaze. This is for the Orange trail. You will see this blaze on some sections where the Orange trail converges with other trails (mostly on the BLUE trail).
IMPORTANT: There is one small section (3/10 mile) of the course that is only on the ORANGE trail. In 2018 the blue trail was expanded by 2 miles to 15.1 miles(This section is shown on the course map as a dashed blue line.) To keep the course the same length this has required us to use a 3/10 mile section of the ORANGE trail bypassing these 2 new miles of trail. The ORANGE BYPASS starts at around 9 miles into the Blue trail and continues until 9.3 miles. This will be marked with arrows directing you onto the ORANGE bypass and back onto the BLUE trail at the end of the bypass. Images of how this was marked in 2019 can be seen below.
Outside of this small section of the Orange trail and any sections that converge with other trails you should NEVER be an an ORANGE ONLY trail. If you are, you have gone wildly off course and will likely be getting a ton of bonus miles. So pay close attention. To visualize this please review the course map for more details.
