Bandera Endurance Trail Race

Bandera Endurance Trail Race

Bandera Endurance Trail Race takes place January 9-10, 2027 at Hill Country State Natural Area in Bandera, Texas. The event offers multiple distances and uses a 50k main loop as its core.

Distances

• 100k, two full 50k laps, 25 hour cutoff
• 50k, one full 50k lap
• 25k, starts with full loop then cutover, rejoins before YaYa aid
• Youth 1 mile

Course and terrain: the main loop is run counterclockwise and has roughly 3,300 feet of elevation gain and loss per 50k lap. Trails are rocky and include sotol and steep short hills; there is one consistently flat section near YaYa aid station. The race is technical with frequent climbs and downhills. Course markings include tape, arrows, and confidence markers; reflective markers are used for nighttime navigation.

Support and logistics: all aid stations offer full support and are placed close to park roads. The series is cupless, so runners should carry a cup or bottle; collapsible SpeedCups are available at packet pickup. Drop bags may be left at many aid stations the day before the race; delivery to two specific aid stations is provided for 100k entrants only. Chip timing uses ankle straps collected on race morning and must be worn on the ankle.

Rules and perks: pacers are allowed for 100k runners after one 50k loop, with age exceptions noted. Finishers of the Bandera 100k who complete the course within 18 hours qualify to enter the Western States lottery. Awards include top overall and age group recognitions.
