About This Race
The Big Texas Ultra presents a unique two-day endurance challenge in the heart of Central Texas, combining Friday's 15K warm-up with Saturday's main events along the scenic Lake Georgetown Rim Trail. Set in the rolling hills outside Austin, this November race offers runners a chance to test themselves against Texas terrain that's more varied than many expect from the Lone Star State. The event's multi-distance format creates a festival atmosphere where 15K runners share trails with 100K ultramarathoners, while the specialized 15K RUCK division adds a military-inspired element. The Lake Georgetown setting provides a backdrop of limestone bluffs and oak-covered hills, typical of the Hill Country region that has become a destination for trail runners seeking technical terrain without extreme elevation. With its moderate November timing, the race avoids Texas's notorious summer heat while capitalizing on the state's most pleasant running weather. The event's structure around Russell Park creates a central hub that allows for good spectator access and crew support, making it appealing to both runners and their support teams.
The race unfolds on the Lake Georgetown Rim Trail system, following established paths through Central Texas Hill Country terrain. The 50K utilizes a loop format beginning and ending at Russell Park, while shorter distances follow an out-and-back configuration on the same trail network. The course traverses limestone outcroppings and oak woodlands typical of the region, with the lake providing scenic relief along certain sections.
