Western States Qualifier

The Brazos Bend 100 miler distance has been an official Western States Endurance Run qualifying race for over five years. Since BB100 is held in early December, around the same time as the WSER lottery, our race will earn you a raffle ticket to the following year's lottery for the next year's WSER. Example: If you qualify in 2023 you will earn a 2024 raffle ticket for the 2025 WSER lottery. Official letter from WSER:

"We [WSER] are pleased to inform you that the 2023 Brazos Bend 100 has been selected as a qualifying race for the 2025 Western States 100. Runners who complete the race within 30 hours will qualify to enter a lottery where the runners for Western States will be selected. You do not need to submit anything to us, we will obtain the results directly from your website.

The qualifying period for the 2025 Western States will be from November 6, 2023 through November 3, 2024. The lottery will be held on December 7, 2024 and the race itself will be run on June 28-29, 2025."


To celebrate the Texas State Parks centennial we are doing a special edition 100k (replacing the 50M) event to pair alongside the 100mi, stay tuned for more exciting updates for this full weekend of racing.
Brazos Bend 100
100 Miler / 100 kilometer / 26.2 Marathon / 13.1 Half Marathon

The Brazos Bend 100 Miler is the FASTEST trail in the nation with its mostly flat course and easy aid stations. It's the perfect place to set some personal records, and there are alligators! The wildlife is abundant in Brazos Bend State Park, but it's overshadowed in general interest by the American alligator. Birds of 290 species have been sighted in and around the park. The diverse habitat is a haven for migratory waterfowl, a variety of shorebirds, wading birds, songbirds, and raptors.
