Bandera Endurance Trail Race 2027

The Bandera Endurance Trail Race takes place in early January at Hill Country State Natural Area in Bandera, Texas. It offers 100K, 50K, and 25K distances, along with a Youth Trail Run for children 12 and under. The 100K begins Saturday as a standalone event, with a 25-hour time limit for completion. The primary 50K and 25K races are held on Sunday. A limited number of participants can join a non-competitive 50K on Saturday, though this entry is not eligible for overall awards. The course features rugged Texas Hill Country trails, reflected in the direct tagline: "No whiners, wimps, or wusses." Organizers characterize the route as demanding, with terrain that can cut, sting, or bite. The 100K attracts participants from across Texas, other states, and internationally. It also functions as a Western States Endurance Race qualifier, contributing to the presence of strong ultrarunners despite a challenging finish rate; in one instance, approximately one-third of 100K starters did not complete the race.
