Event Description
This is the April edition of our popular Brazos Bend races with the marquee event being the 50-mile.
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 easy horse trails. Conditions in the Spring are typically warm and humid but can still start with some cooler mornings. 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!
