"So, the last shall be first, and the first last"
Nestled in the heart of the Texas Hill Country, our event takes place near Lago Vista, just 30 miles northwest of Austin. The course winds around a peninsula jutting into Lake Travis, offering stunning water views and the natural beauty of Central Texas. 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.
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.
Following our successful 2025 inaugural event, we are working toward Bronze Ticket qualifying status for 2026. Check back for updates on our certification progress!
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."
