Brazos Bend 100

This is the December edition of our popular Brazos Bend races with the marquee event being the Wester States Qualifier 100 Mile event.

The Brazos Bend course is the fastest trail in Texas trail running. The course is 99.9% flat, and the only hill is 10 feet. Other than that you will be running on flat surfaces that move from hard crushed rock, soft hiking trails under tree canopy, and smooth horse trails. Conditions in December can have a mix of anything but are typically great conditions for running. Brazos Bend is a spectacular State Park located just South of Houston/Sugar Land and is most known for its abundance of birds and American Alligators among other wildlife. The gators are a part of our race, there has never been an incident in the park. Enjoy them on your run, from a distance, and you may get some unique race photos!
