• Trail Description: The Brazos Bend 100 is the largest trail race in Texas and one of the fastest trail races in the world on flat and smooth trails with incredible support from four aid stations per loop.
• Course Details: The course is 99.9% flat, with the only "hill" being a 10-foot rise over 0.1 of a mile. The rest of the ~16.7mi loop consists of hard crushed rock, soft hiking trails under tree canopy, and smooth horse trails.
• Shoe Recommendation: Most runners get away with a road shoe. Conditions in December can vary but are typically great for running.
