We have truly found one of the most beautiful, serene, interesting natural areas in Texas. Reveille Peak Ranch has a huge granite dome (2nd largest in the region) that we run you all up, around, and over throughout the course. When you’re not in the ever-changing rock features, you’re winding through beautiful hill country forest, through streams, wild flowers, and around a lake. To top it all off, we start and finish next to the lake in the Pavilion complete with a swimming pool touching the edge of the finishing chute! Plan to stay a while after the event. Perfect race to truly challenge yourself and spend some time with new and old friends!
