Austin's Backyard Ultra & Memorial Day Remembrance Run

Austin's Backyard Ultra is a last-person-standing endurance event held at Turkey Bend LCRA Recreation Area near Lago Vista and Marble Falls, Texas. The format uses a unified loop of approximately 4.2 miles (about 6.7 km) that starts anew at the top of each hour. Participants must complete each loop within the hour to continue; failure to finish a loop in time or to start the next loop results in elimination.

The Memorial Day Remembrance Run uses the same course and offers timed-free distances on the unified loop. Distances offered:

  • Marathon : 26.2 miles
  • Half Marathon : 13.1 miles
  • The 8 Mile March
  • The 4 Mile March

The course follows a peninsula along the Colorado River and alternates open wildflower meadows, lakeside views, and Hill Country woodland. Terrain includes mixed trail and paved surfaces with some technical sections and rolling grades. Reflective markers assist nighttime navigation. A central start and finish corral anchors the course near main campsite clusters and serves as the crew area between loops.

Support and rules include stocked aid stations, required lighting for night loops, a minimum carry of 20 oz (≈600 ml) per loop, and mandatory electrolyte replenishment for longer efforts. Tent and crew area is designated near campsites 20 to 29 with a maximum of one tent and one table per participant or crew. Finishers earn custom commemorative items and event shirts based on distance completed. Visit the organization's website for the most recent information.
