Race Information

The only Race in the World that starts in a Cave's belly. Enter Texas's largest Caverns and descend to Pluto's anteroom. The event features a 5k, 10k, and Half Marathon that run on the private property of Natural Bridge Caverns. The 5k course is mainly on jeep trails that make 1 loop and finish in the NBC Village. The 10k is an out and back with one nice hill that merges onto the 5k course and finishes in the NBC Village. The Half Marathon covers every type of terrain, and the beauty of the Hill Country is stunning.
