Austin's Backyard Marathon Ultra • Full • Half & Memorial Day Remembrance Run 4 Miler • 8 Miler

The Last Person Standing Challenge in the Texas Hill Country near water views tests mental fortitude, strategic pacing, and physical endurance. The Day Loop offers expansive views and technical engagement around the Colorado River. The Night Loop shifts to the park's interior spine for tunnel vision and headlamp navigation. The transition between loops is where the race is often won or lost, demanding a moving meditation to conquer the long hours.
