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

The courses run along a peninsula at Turkey Bend LCRA Recreation Area, tracing the Colorado River through wildflower-lined meadows and shaded Hill Country woodland. The terrain rolls throughout, with lakeside views opening up between wooded stretches. The Memorial Day distances all follow the same trail as the backyard ultra, so the course has already been run hard before the morning crowds arrive.

The backyard ultra runs through the night, with reflective markers on course and a central start and finish corral near the park's camping area serving as home base between loops. Crews stage there to resupply runners. The Remembrance Run begins at dawn with a moment of silence before the field heads out on the same trail.

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

Will I finish last at the Austin's Backyard Ultra • Marathon • Full • Half & Memorial Day Remembrance Run 4 Miler • 8 Miler?

Almost certainly not. Half the 26.2 Miles field finished slower than 5:07:59, and the last recorded finisher came in around 7:17:58, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.

Is the Austin's Backyard Ultra • Marathon • Full • Half & Memorial Day Remembrance Run 4 Miler • 8 Miler a good first 26.2 Miles?

It is a small race (14 finishers), which is friendlier and less intimidating than a big-city event, though the field thins out. There is no qualifying time, and the finish-time spread above shows how varied the field really is. If it is your first 26.2 Miles, that spread matters more than the winner's time.

How competitive is the Austin's Backyard Ultra • Marathon • Full • Half & Memorial Day Remembrance Run 4 Miler • 8 Miler?

The 26.2 Miles winner ran 2:31:00 while the median finisher took 5:07:59. That spread points to a broad, mostly recreational field rather than a race dominated by club runners.
