From the Organizer

In 2004, a wild idea was hatched: an ultra trail race in Big Bend. It had never been done. The logistics were impossible. Big Bend national and state parks are huge: over 300,000 acres and several hours from San Antonio. Water is scarce. Fuel is scarce. Transportation is scarce. The isolation also means it has lowest light pollution of any park in the lower 48 states: making it a fantastic place for stargazing. This was the beginning of a truly great event that has been held annually ever since. This year Carroll Voss, Erik Stanley, and the team of volunteers and competitors with Trail Roots are looking forward to the best race yet.

Trail Running

Running off-road — dirt, singletrack, and mountain paths — from 5Ks to ultras. The terrain makes for an exciting twist and adventure in your running journey.
