Big Bend Ultra is a running, trail running, and ultra race on January 17, 2027 in Terlingua, TX, with entry fees from $110 to $210.
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.

From Endurance Grid
This race spans more than one sport — here’s a guide to each, so you can understand what’s involved and decide if it’s the right fit. For course distances, logistics, and race-day specifics, always defer to the race organizer’s event page.
From 5K to marathon, running races are an accessible entry point into endurance sport. There's a distance for every fitness level and a community at every start line.
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.
An ultramarathon is anything beyond the standard marathon — 50K, 50-mile, 100K, 100-mile, and timed events. Crossing the line is less about speed and more about not quitting.
