The Beast of the Brazos is an open-water swimming event in Waco, Texas, celebrating its anniversary with courses that reflect the IRONMAN and IRONMAN 70.3 Waco. Participants receive a swim cap, dri-fit shirt, and finisher's medal. Wetsuit classifications affect eligibility for top age group awards, though participants can change classification on race day. If water temperatures exceed 90 degrees, the course may be shortened for safety. Proceeds support the Greater Waco Sports Commission, a non-profit organization focused on enhancing community life through sports and exercise.
