A fast, flat 100K through alligator country in Brazos Bend State Park
The Brazos Bend 100K follows the same flat, fast loop course as the 100-mile through Brazos Bend State Park south of Houston. Runners navigate a mix of crushed rock, hiking trails, and smooth horse trails sharing the route with the park's famous resident alligators. With a 31-hour cutoff and a pacer allowed on the final loop, this is an accessible and well-supported ultra for runners looking to tackle their first or fastest 100K.
