Brazos Bend 100

The Brazos Bend 100 is a premier ultra trail running event held annually in December at Brazos Bend State Park, just south of Houston, Texas. Known as one of the fastest trail 100-mile races in the country, the course is nearly flat (99.9%) with only a minor 10-foot hill, featuring a mix of hard crushed rock, soft hiking trails under tree canopy, and smooth horse trails. Distances offered include 100 miles, 100 kilometers, marathon, half marathon, and a women's sub-ultra half marathon.

The race is a Western States Endurance Run qualifier for sub-32-hour 100-mile finishes. Runners enjoy scenic wildlife views, including American alligators, with strong support from four aid stations per loop. The event also offers cash prizes and finisher awards.
