The Race

The Course

Come run in a prehistoric area dating back some 10,000 years where Indigenous people left cave art as evidence of their presence tucked into the weather beaten Chihuahuan Desert, the second largest desert in North America!


Experience the uniqueness of the desert wildlife and flora, be awe inspired by the incredible views of Seminole Canyon meeting the Rio Grande River, and view, at a distance, cave art as you traverse this loop course over technical single-track trail and backcountry jeep roads.


This is a bucket list event that you don’t want to miss. 


Note: You DO NOT need a passport for this race. However, if you would like to visit Mexico via the border crossing in Del Rio, Texas you will need a valid passport.
