Texas Hill Country Paradise

Experience the perfect blend of challenging terrain and breathtaking landscapes that will keep you motivated hour after hour.
Join us for Austin's Backyard Marathon & Memorial Day Remembrance Run, a unique endurance event that allows you to push your limits in the beautiful Hill Country. This officially sanctioned Backyard Ultra is not just a race, it's a test of mental fortitude, strategic pacing, and physical endurance that will challenge you in ways you've never experienced.
The Backyard Ultra Format
Last Person Standing Challenge
This is an officially sanctioned Backyard Ultra. Complete each 4.167-mile loop within 60 minutes to continue. A new loop starts at the top of each hour.
The Austin Backyard Ultra at Turkey Bend Recreation Area utilizes a dual-course strategy to manage the unique physical and mental demands of a last-person-standing event. This format requires runners to complete a 4.167-mile loop every hour on the hour, and the transition between the Day and Night loops marks a pivotal shift in the race's narrative. By splitting the event into two distinct environments, the course design addresses the changing light conditions, runner safety, and the psychological "wall" that often hits during the transition from dusk to dawn.
The Day Loop is defined by its expansive views and technical engagement, tracing the perimeter of the Colorado River. Runners navigate a mix of winding single-track and open meadows that offer constant visual stimulation, which is essential for staying mentally "awake" during the early hours of the race. The terrain and occasional root-tangled sections through the northern wooded "hook" provide a classic Central Texas trail experience, rewarding those who maintain a steady, efficient gait while soaking in the waterfront scenery.
As the clock strikes 7:00 PM, the race shifts to the Night Loop, moving away from the exposed lakeside to the interior "spine" of the park. This course is built for "tunnel vision," prioritizing wider double-track and fire-break paths that are easier to navigate under the beam of a headlamp. While this loop may feel more repetitive, its predictability is a safety asset; it minimizes the risk of trips and falls when fatigue begins to compromise a runner’s proprioception and balance.
The transition between these two loops is where the race is often won or lost. The psychological shift from the "exploratory" feel of the Day Loop to the "rhythmic grind" of the Night Loop can be jarring, especially as the Central Texas humidity lingers after sunset. Successful runners treat the Night Loop as a moving meditation, relying on the high-visibility reflective markers to guide them through the darkness while the interior woods provide a natural windbreak and a quieter, more sheltered environment for the long midnight hours.
Logistically, both loops are anchored by a central start/finish corral located near the park’s main camping clusters to ensure seamless crew support. This "home base" serves as the emotional heart of the event, where runners can refuel and reset in the brief window between yards. Whether navigating the scenic riverside in the midday sun or grinding through the wooded interior under a canopy of stars, the dual-course layout ensures that the Austin Backyard Ultra remains a dynamic and strategically challenging test of endurance.
Memorial Day Remembrance Run

While the last runner standing wins the overall championship and qualifying spot, you're welcome to participate according to your own goals. Many runners choose to complete a specific number of loops rather than competing in the last-person-standing challenge.
You'll earn recognition based on your achievement: Complete 1 loop (4-miles) for a woodallion, 4 loops for half marathon medal, 7 loops for marathon medal, or 8+ loops for ultra medal. Simply notify race staff when you've reached your personal goal.

"This variation in terrain, from exposed shoreline paths to shaded and paved sections, will provide crucial diversity over extended hours of running. The course change also gives runners a mental reset, which can be psychologically significant in a format that tests mental endurance as much as physical stamina."
