Big Bend Ultra, Terlingua TX
Big Bend Ultra is an annual series of trail races and ultras held in the Big Bend region near Terlingua, Texas. The event traces its origin to 2004 and has been organized each year since. It takes place within and around very large national and state park areas totaling over 300,000 acres and is several hours from San Antonio. The location is remote; water, fuel, and transportation are scarce and light pollution is very low, making the area notable for stargazing. Organizers with Trail Roots work with volunteers and competitors to stage the races.
Races are offered across multiple distances. Registration for these races opens July 4, 2026 and closes September 27, 2026. Registration fees vary by distance and range from $110 to $210.
