The trails in the LBJ National Grasslands are named by color. The Grasslands Trail Run uses the blue, white, yellow, and red trails. Each trail is marked using color-coded tree markers and streamers. Be sure to watch for these course markings—you should never go more than ¼ of a mile without seeing a marking. Keep your eyes open and remember—don’t just follow the runner in front of you. They might not be paying attention!
