About This Race

The Beast of the Brazos stands as Central Texas' premier endurance challenge, drawing runners to the rolling hills of Cameron Park in Waco. This well-established event offers six distinct distances ranging from a trail 5K to the signature 50-mile "Beast," all utilizing the same 10-mile loop system that starts and finishes at the Cameron Park Redwood Shelter. As part of the prestigious Texas Legends Series, the race has built a reputation for showcasing the rugged beauty of the Brazos River valley. The loop-based format allows for excellent spectator and crew support while testing runners' mental fortitude through repeated terrain. The event's multiple distance options make it particularly appealing to running groups and clubs, where members can tackle different challenges while sharing the same start line and post-race celebration. The race's April timing takes advantage of Texas' mild spring weather, though runners should prepare for potential variability typical of Central Texas springs. The park setting provides a more intimate atmosphere than many larger ultras, with the 100-participant cap ensuring a community-focused experience where every finisher is celebrated.

The course consists of a 10-mile loop through Cameron Park's trail system, beginning and ending at the Redwood Shelter. While specific elevation data is not available, the terrain follows the natural contours of the Brazos River valley, featuring the characteristic rolling hills of Central Texas. The course runs entirely on paths according to ITRA classification, providing a pure trail running experience without road sections.

Runners completing longer distances will navigate the same loop multiple times, with the 50-mile "Beast" requiring five complete circuits. This format allows participants to become familiar with the terrain while providing mental challenges inherent in loop-based racing.
