Created in 2023 as a fatass event, BABU is a collaboration between Skybreaker Racing and Auburn Area Trail Runners. This new 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.
