Brazos Bend 100

Brazos Bend 100 is Trail Racing Over Texas's December edition held at Brazos Bend State Park, just south of Houston. The marquee events include 100M, 100K, 26.2M, and 13.1M, with a Brazos Bend Kids Kilometer and an Ultra Pacer as extras. The course is famously flat and fast—99.9% pancake-flat—with a single 10-foot rise per loop and runs on hard crushed rock, shaded hiking trails, and smooth horse trails around four fully stocked aid stations per loop.

The race is a Western States Endurance Run qualifier and takes place amid wildlife and birds in the park. Spectators and volunteers help create a welcoming, supportive vibe. Visit the organization's website for the most recent information.
