Ready to Conquer the Beast? 

Take on the challenge of the Beast of the Brazos Open Water Swim in the heart of Waco, Texas. Whether you're looking to test the waters with the 750-meter swim, train on the 1.2-mile course that mirrors the IRONMAN 70.3 Waco swim, or challenge yourself with the 2.4-mile distance that replicates a full IRONMAN swim, there's a race for every level of swimmer. 

Held in the scenic Brazos River, Beast of the Brazos offers a unique open-water experience for first-time participants and experienced athletes alike. All registered participants will receive an official event swim cap, dri-fit shirt, and finisher medal.

Overall awards will be presented to the top male and top female finisher in each race distance in the non-wetsuit category. Athletes receiving an Overall Award are not eligible for Age Group Awards. 

Age Group Awards will be presented to the 1st, 2nd, and 3rd place male and female finishers in each non-wetsuit age group category and race distance. 

Participants competing in a wetsuit division are not eligible for Overall or Age Group Awards. 

Please note: Awards must be picked up during the awards ceremony. Awards will not be available at the After Party. If you are unable to pick up your award during the ceremony, it can be mailed to you at your own expense. 

If you intend to switch from the wetsuit to non-wetsuit category on race morning, there is no penalty, but you must inform race staff before packet pick-up and registration closes the morning of the event at the Registration & Packet Pick-Up Tent. Please consult the event schedule for exact packet pick-up times on race day to ensure any changes are submitted on time.

For safety reasons, athletes will not be permitted to increase their race distance within two (2) weeks of the event or on race day. This restriction does not apply to athletes who choose to switch to a shorter distance; however, switching to a shorter distance will not result in a refund.

If the water temperature is above 90 degrees, the course will be abbreviated for safety reasons.
