About This Race
The Big Texas Ultra transforms Georgetown's Lake Georgetown Rim Trail into a weekend celebration of endurance running. This two-day event offers multiple ways to challenge yourself, from a Friday 15K warm-up to Saturday's main attractions spanning 15K, 50K, and 100K distances, plus a distinctive 15K ruck option for those seeking a different kind of challenge. The course architecture is elegantly simple: a 15K out-and-back section forms the foundation, with longer distances adding loops to create the desired challenge. All routes begin and end at Russell Park, creating a festival atmosphere where runners can support each other across different events. The Saturday lineup accommodates various goals, whether you're testing yourself at a new distance or pursuing a championship-level 100K effort. Set in the hills of Central Texas, this race showcases the region's characteristic landscape while maintaining accessibility for runners across experience levels. The early November timing captures Texas at its most temperate, before summer heat but after the worst of hurricane season, making it an attractive destination race for those seeking reliable weather conditions.
The Big Texas Ultra utilizes the Lake Georgetown Rim Trail system, creating courses that range from a straightforward 15K out-and-back to complex loop combinations for the ultra distances. The 15K route serves as both a standalone race and the building block for longer events, while the 50K incorporates a loop structure that begins and ends at Russell Park.
The trail surface is entirely path-based, providing consistent footing without the technical challenges of rocky singletrack or the monotony of paved surfaces. The course design allows for excellent spectator and crew access at the start/finish area, while the loop structure means longer-distance runners pass through the aid station multiple times throughout their event.
