This backyard ultra takes place at Dry Creek Parkway, in Rio Linda, California (northern Sacramento).
In the traditional style, runners will have one hour to complete each 4.16 mile loop. Each new yard (loop) will begin every hour, on the hour. If a runner is not in the start corral, ready to begin the next yard, on the hour mark, they're out. The runner who completes the most yards wins.

History: B.A.B.U. was originally created in 2023 as a fatass event. In 2024 it was made an official event as a collaboration between Skybreaker Racing and Auburn Area Trail Runners. In 2025, while the event was still put on by the same organizers, through partnership, BABU fell under the Singletrack Running umbrella. Since then, BABU is back under the Skybreaker Racing name.
