The Race

The Course

The Austin Falls Ultra is the perfect mix of a destination Ecoregion Race and an Urban Trail Race. This race takes place in the McKinney Falls State Park, only minutes from downtown Austin.


Within the naturally rugged trails of the Texas hill country, you’ll navigate a technical single track trail protected by lush green foliage and diverse scenery. Rolling and winding through the course, you’ll dodge roots and rocks, ascend and descend hills and run across wooden bridges. Be prepared for a possible water crossing of the falls (dependent on rain).

After the race, have fun jumping off cliffs in the cool, refreshing pools of the Onion Creek.
