About the Event

In 2004, a wild idea was hatched: an ultra trail race in Big Bend. It had never been done. The logistics were impossible. Big Bend national and state parks are huge: over 300,000 acres and several hours from San Antonio. Water is scarce. Fuel is scarce. Transportation is scarce. The isolation also means it has lowest light pollution of any park in the lower 48 states: making it a fantastic place for stargazing. This was the beginning of a truly great event that has been held annually ever since. This year Carroll Voss, Erik Stanley, and the team of volunteers and competitors with Trail Roots are looking forward to the best race yet.

About Terlingua

Learn more about the host city, Terlingua.

Terlingua is a mining district and census-designated place (CDP) in southwestern Brewster County, Texas, United States. It is located near the Rio Grande and the villages of Lajitas and Study Butte, Texas, as well as the Mexican state of Chihuahua. The discovery of cinnabar, from which the metal mercury is extracted, in the mid-1880s brought miners to the area, creating a city of 2,000 people. The only remnants of the mining days are a ghost town of the Howard Perry-owned Chisos Mining Company and several nearby capped and abandoned mines: the California Hill, the Rainbow, the 248, and the Study Butte mines. The mineral terlinguaite was first found in the vicinity of California Hill.
