Austin's Backyard Ultramarathon – Waiting List
This event supports a first-come first-serve waiting list.
You can join the waiting list now.
Selection from the waiting list starts on April 28, 2026 at 11:00am CDT.
To be considered for a spot in the Ultra, you must be registered for the Full Marathon.
Why? Because if a spot opens up on May 22nd, we need a runner who has already put in the work. Being on the waitlist doesn't guarantee a call-up, but it guarantees you're in the conversation.
If you get called up, your Marathon spot converts. If you don't, you still get to test your grit on the same trail, on the same day.
